God Bless all those who serve our country ~ and that means each of you as well, whether you be a fireman, police officer, doctor, lawyer, farmer, housewife, blue collar, or white collar worker, it takes hard work to own, operate, or work for someone else so we can bring smiles to those around us and give our families what they need and deserve. As May is upon us, I seem to remember (and this was many moons ago) we had a parade in the small town of Vincentown, NJ. In that parade, were two young girls. Yup, you guessed it ~ one of them was me, and the other was my best friend Rita. We weren’t rich by any stretch of the imagination. Rita’s father worked at the chemical plant a short way from her home; my mom and dad both worked at J & H Garage. They owned it, I’m very proud to say. Rita and I would fancy up our bikes, and dad would put them in the back of his truck and drive us to the starting point of the parade ~ known as The Memorial Day Parade. On the ends of the handles of the bikes were long colored strings of some sort, red, white, and blue; and in the spokes of the wheels were colored pieces of cardboard or paper as I remember. Those memories of days gone by and the smiles on people’s faces watching in awe of that small town parade honoring the fallen. Always work hard for our country. Stand up for what you believe in. It’s the right thing to do. Stay Safe.

7 MAY 2021 WorldWide Drilling Resource® Mud Pumps Keep HDD Operations Cool Adapted from Information by Gardner Denver Horizontal directional drilling (HDD) is used for many different projects. Utility contractors use this method to install cables and pipelines, while construction companies use HDD to place highway ducts, and water lines under existing roads, rivers, or other sensitive areas. The gas and oil industry has used HDD technology to increase production from underperforming wells, and environmental remediation of contaminated sites is another beneficial use of HDD. The process involves boring a tunnel beneath the surface and placing a conduit in the borehole to pull the product into position. This reduces surface damage and eliminates the need for trenching. HDD pumps - also known as drill pumps, mud pumps, and high-flow pumps - are an essential component to HDD operations. Boring underground requires drilling fluid combining water and bentonite clay to remove cuttings, stabilize the borehole, cool the cutting tools, and lubricate the pipe string. Most mud pumps are positive displacement, reciprocating pumps comprised of a power end and fluid end assembly. A diesel engine or electric motor acts as the pump power source. The power end converts the rotation of the driveshaft to a reciprocating motion by using a crosshead assembly. The fluid end uses this reciprocating action to achieve the function of pumping the pressurized mud. The fluid end assembly is comprised of a suction and discharge module, manifolds, pistons, liners, and valve assemblies. Most of the fluid end assembly components are high-wear items. The drilling pump rotates the drill bit which removes the material. As the drill bit is rotating, the pressure and fluid produced by the drill pump help stabilize the tunnel. The mud extracted from this process is then filtered and reused for drilling fluid. A drilling pump should be able to provide a constant flow rate of fluid at a specific pressure. Over the past century, numerous mud pump design configurations have been introduced. The most common designs on the market today are duplex, triplex, and quintuplex models. The designs have horsepower ratings from 750 - 2400 horsepower.

8 MAY 2021 WorldWide Drilling Resource® MamaJo, Protector of Rivers Adapted from Information by the City of Fort Wayne, Indiana Fort Wayne, Indiana’s Three Rivers Protection & Overflow Reduction Tunnel (3RPORT) and the Tunnel Works infrastructure project are designed to complete a large tunnel located in the bedrock below the city. An associated network of pipes nearer the surface will collect and transport sewage from locations where the combined sewer system might overflow during wet weather, thus reducing the amount of combined sewage discharged into Fort Wayne’s rivers by 90% in a typical year. The five-mile tunnel alone, a central feature of the project, is a massive undertaking; 3RPORT will run parallel to the St. Marys and Maumee Rivers and is being constructed in bedrock approximately 200-220 feet belowground using a tunnel boring machine (TBM). The tunnel, lined with concrete and 16 feet in diameter, will collect and transport combined sewage. Seven drop shafts, four to eight feet in diameter, will direct sewage and excess rainwater from near-surface sewer pipes into the tunnel, which will then transport the combined sewage to the treatment plant. The TBM was affectionately nicknamed MamaJo, by taking the first two letters from Fort Wayne’s three rivers, the Ma from Marys, Ma from Maumee, and Jo from Joseph. It has been a tradition to name the tunnel boring machine since mining lore as far back as the 1500s says workers prayed to St. Barbara for protection while working in the dark underground. MamaJo, standing at a diameter of more than 20 feet and stretching more than 400 feet in length, has been steadily boring 24 hours a day through the bedrock. As of December 5, 2020, MamaJo hit the three-mile mark. Tunnel completion is expected sometime this year. The intricate connection to neighborhood sewers is projected for completion in 2023, and the tunnel should be operational that same year. Construction of the entire system of drop shafts, consolidation sewers using the traditional method of open-cutting a trench and installing pipe, and the five-mile tunnel began in 2018. While the tunnel should be operational by 2023, all parts of the Tunnel Works system, including drop shafts and associated pipes, will be completed and operational by 2025, at an approximate cost of $188 million. When completed, this deep-rock tunnel will be a significant part of the effort to clean up Fort Wayne’s rivers and protect neighborhoods from basement backups and street flooding.

9 MAY 2021 WorldWide Drilling Resource® SOS from a Contractor by Troy Cunningham, President, Teddy Bear Timber Corporation Workforce of today To Whoever Finds This Important, I am a small business owner, also a retired Fire Lieutenant here in Florida. I find myself sitting here wondering why there are no people applying for a job. See, we had one of the worst hurricanes hit our area about 2-3 years ago. At the time, just before the storm, we had five employees. Just after the storm, when most businesses were having to keep their doors shut because they had no building to work out of, we hired five more employees to assist our community in rebuilding and also giving jobs to those who lost or needed a job. One year after the storm, we had only lost three employees. Then once COVID hit, we had only five employees; once the first assistance check was received, we had employees laying out. We decided we needed to bluff a drug testing (random) on our employees. Once we told them about this move, we had a mass exodus! We ended up with one employee left. Now, two months later, we have none. I am trying to understand why our government is paying people to sit at home, get a check, and spend the money on drugs, which causes problems all the way around. Also, some of these employees live in government-assisted housing that states you cannot have any illegal drugs in the house. These people are sharing videos online with them doing drugs in the house with multiple people. I didn’t mention the people have their young children in the room while doing the drugs. We have called the local police department about the matter, and they say the district authorities wouldn’t prosecute for this action. Also, the people are letting their kids live in pure filth (roaches, urine, garbage everywhere, and drugs on the counter). My main concern is that we, as a society, have created this problem by looking the other way. I know for a fact other companies, much bigger than mine, don’t care and turn a blind eye to this problem. Their motto is, “As long as the work is getting done, I don’t care.” Some of these companies are doing work for our government facilities. I, a rule, regulation, and law follower, am the one penalized. See, if I fire someone, all they have to do is file unemployment and they will get it. Then my rates go up. We, as business owners, are held hostage and don’t know what to do. Your input would be greatly appreciated. What do we do as struggling American Business Owners? Please send replies to SOSfrom a Contractor to Michele@worldwidedrillingresource.com Trade Show Date & Location Changes! While the Made in America Team was excitedly preparing for the Made in America 2021 trade show event, it became necessary to make a major change to the venue. They are grateful to Detroit for allowing them the opportunity to host the event, but having to change the date from the first week of October to the third week, posed significant challenges to this year’s mission. The Made in America 2021 three-day event will start on Friday, October 1 (National Manufacturing Day 2021), in the new Kentucky International Convention Center (KICC), in downtown Louisville, Kentucky. Louisville has enjoyed a rich manufacturing tradition of excellence and is home to more than 1300 manufacturing companies. The city is also within easy driving distance of several major manufacturing hubs. Made in America 2021 has an audience of manufacturing professionals, celebrities, consumers, businesses, media, and government.

11 MAY 2021 WorldWide Drilling Resource® Blasting Through 2020 ~ A Look Back at Significant Innovations Compiled by Carol C. Schimpf, Editorial Assistant WorldWide Drilling Resource® The year 2020 may have been a dud for many, but the drill and blast folks did not sit by idly waiting it out. Several significant innovations burst through the dark haze of the pandemic and presented improved safety and efficiency for blasting. These technologies can remove the need for mine workers to be close to the hazardous conditions created by drill and blast activities, and autonomous drill and blast systems do not need breaks, shift changes, or other human workforce necessities. Add in the enhancements these systems offer for precision and consistency, and it’s no wonder many projects have been launched to drive innovation in this area. Leti, a research institute of the French Alternative Energies and Atomic Energy Commission (CEA), and Davey Bickford Enaex, part of Chile-based global explosives and blasting solutions major Enaex, announced they have a new, wireless system offering increased safety, flexibility, and productivity gains to the blasting market. The new system consists of electronic detonators with bidirectional radio modules placed on the mining pit’s surface. The wireless network communicates with a digital blasting system located a few miles away from the blasting zone and is controlled by a wireless communication protocol specifically developed and optimized to ensure safe, reliable, and synchronized operation of hundreds of detonating elements in open-pit mines. The key innovation is the wireless activation of the detonators, which can be powered up, programmed, and reconfigured by means of an easy-to-use remote programming unit operating through a safe and dedicated optical link. In Australia, Newcrest Mining’s Cadia Valley underground mine in New South Wales successfully tested new technology from MacLean Engineering and Orica in a 30-day evaluation. The site used remote drilling, loading, and wireless blasting to remove workers from major hazards. As part of the trial, Newcrest tested MacLean’s new secondary break drill and blast system, Automated Explosive Charger, as well as Orica’s Wireless Blasting System (WebGen 100). Secondary break activities are used when oversized rocks require explosives, with workers accessing the area to wire up each conventional explosive used. MacLean’s system removes workers from these secondary break activities. Using a prototype “bolt-on” piece of equipment which attaches to existing secondary break drill rigs, the Auto Explosive Loader can drill a hole into a rock and push the wireless explosive inside the hole without the operator leaving the cab of the drill rig. After the operator removes the drill rig and leaves the area, the explosive can be remotely detonated using a wireless device by Orica. Orica also teamed up with Epiroc to develop a prototype of the world’s first semiautomated explosives delivery system, Avatel™. The system provides complete and repeatable control over blast energy from design through to execution. Avatel is a twin boom, semiautonomous and fully mechanized development charging solution allowing a single operator to complete the entire charging cycle from the safety of Epiroc’s enclosed Roll-Over Protection Structure and Falling Object Protective Structure certified cabin. Automated or digitized drill and blast operations have the potential to improve productivity and increase profit margins at mine operations while enhancing worker safety. As 2021 charges ahead, these innovations promise to ensure the right explosives will be safely delivered into the right holes, given the right timing to achieve optimal efficiencies, and yield the desired outcomes.

Environmental Monitoring by Thomas Kwader, Ph.D., P.G. Owner, Qwater Well Developer and WorldWide Drilling Resource® Hydrogeologist Specific Capacity - A Measure of the Health and Efficiency of a Well, Part 1 of 2 Well Specific Capacity is a measurement of how much water a well can produce at a given pumping rate. For example, if a well is pumping 50 gallons per minute (gpm) and draws down (dd) 10 feet, the well’s specific capacity (SC) is said to be: [5 gpm per foot of drawdown or SC = 5 gpm per ft: dd] The higher the specific capacity, the more efficient the well. Specific capacity should be measured after the pumping water level reaches a relatively constant depth in the well, while maintaining a constant pumping rate. A valve located on the discharge side of the pump may be needed to adjust the flow to maintain a constant water level. If additional flow is desired from the well, the specific capacity of the well can be useful to calculate the size of the pump necessary to obtain the maximum pumping rate the well can sustain. Some wells will reach a “stable” water level in a few minutes, while other wells may continue to draw down for an hour or more. If the well continues to draw down for a long time, this indicates the cone of depression is growing to increase the size and slope of the cone of depression (or funnel) to supply water to the well. I have seen screened wells pumping at one gpm drawdown continuously until the 50foot-deep well went dry; and I have seen fractured rock wells stabilize with less than one foot of drawdown in less than one minute, while pumping in excess of 1000 gpm. These are reasons why a pump test is highly recommended on a new well to determine the optimum size of the pump needed to obtain the maximum pump efficiency. Be sure to confirm, before any specific capacity test is conducted, that the well is fully developed to remove all drilling mud and formation “fines” in and around the borehole. Thorough well development is necessary on all newly drilled wells before specific capacity data is collected. If a new well is not producing much water and continues to draw down significantly for more than 15 minutes, there is a good chance the well is not fully developed. It should also be noted, an undeveloped well will have a lower pumping level which will also require more “lift” and electricity (watts) to operate in the years to come. Well Specific Capacity is the most important measure of a well’s capacity and efficiency, and an indicator that if a well begins to cavitate in the future, water levels may have dropped or the well needs to be redeveloped.

14 MAY 2021 WorldWide Drilling Resource® Environmental Approval for Marimaca Copper Adapted from Information by Marimaca Copper Corporation Marimaca Copper Corporation announced in late 2020, approval for its new exploration campaigns, encompassing further drilling at the Marimaca Oxide Deposit (MOD) and exploratory drilling at the Marimaca Sulphide Target and broader Marimaca District. They are anticipating drilling on the exciting new targets identified through recent magnetic surveys indicating a major copper sulphide target in Antofagasta, Chile. The company successfully completed the Declaración de Impacto Ambiental (DIA) process. This included a rigorous environmental baseline study, including flora and fauna studies along with other potential environmental impacts indicating the project was unlikely to have any significant impacts on the local environment. Additionally, archeological baseline studies were completed with no relevant archeological findings. The company believes this approval will pave the way for less complex future permitting programs. DIA approvals cover almost 9400 acres of highly prospective ground. These include defined district areas around the Marimaca Project, the Marimaca Sulphide Target, and all of the new targets generated to the north of Marimaca. A part of the approval granted construction of up to 365 drill pads over the next three years. Exploration work at the MOD will include an infill drilling campaign ahead of a prefeasibility study. Currently, the company plans to complete the infill drilling sometime in 2021. To prepare for their drilling, Marimaca completed an induced polarization survey to refine drill hole location and orientation along with downhole magnetic susceptibility measurements to identify possible drilling zones. Further surface geological work at the regional targets to the north of the Marimaca Oxide Project helped to pinpoint priority targets. Marimaca’s geological team conducted sampling and completed geological mapping, providing more granular detail of the key geological features of these targets. Hayden Locke, president of Marimaca Copper commented, “2021 is going to be an exciting year in our development as we hope to make another significant copper discovery to complement the unique Marimaca Oxide Deposit, which boasts industry-leading capital costs and bottom quartile all-in-sustaining cash operating costs.” EXB Marimaca open-pit copper oxide mine.

Pumps in the Gas and Oil Industry Adapted from Information by DAE Pumps Pumps are necessary components inside an oil drilling rig. They’re designed to accelerate fluid transferring from one location to another. Let’s explore the different types of pumps used by gas and oil operations, their primary function, and the pros and cons of each model. Centrifugal Pump - The most common type of pump in the gas and oil industry is the centrifugal pump. These pumps contain one or more impellers. Fluid is drawn into the suction end of the pump and then, through centrifugal force, it is forced out of the discharge end. This design allows the pumps to be used for a wide range of applications and are preferred for processes handling low-viscosity liquids and high flow rates. Oil Pump- A standard oil pump mechanically lifts liquid out of the well when there isn’t enough ground pressure to force it to the surface. They are used in areas where oil is abundant, but the ground needs help releasing it. Depending on the depth and weight of the oil, these pumps are capable of delivering one to ten gallons of fuel with every stroke, known as a “walking beam.” Positive Displacement Pump - In contrast to centrifugal pumps, positive displacement pumps don’t use impellers to move fluid, but rather, rotating or reciprocating parts to push / transport liquids. This creates pressure, which moves the liquid to its destination. Positive displacement pumps are perfect for higher viscosity liquids transported at a lower flow rates and are not typically used in high-flow situations. These pumps are also more compact, which increases the high-pressure ratio, making them one of the most efficient types of pumps. Although they are affordable and efficient, positive displacement pumps require extensive maintenance, partly due to mechanical part failures. Oil Transfer Pump- An oil transfer pump transfers glycol from the well to a holding tank during refinement. These pumps work by creating a variation in pressure, pushing the fluid from one location to another. Industrial-scale slurry pumps can operate on electric, solar, hydraulic, or gas power. Since the components are built using corrosion-resistant metals capable of withstanding hazardous environmental conditions, transfer pumps are generally used to move flammable or corrosive liquids like oil, gas, or chemicals. The high volume of activity also means they require extensive maintenance and repairs. Diaphragm Pump - A diaphragm pump is a type of positive displacement pump which uses both a valve and a An oil pump in Utah’s Red Rock Desert.

diaphragm to pull gas and oil into a refinery chamber. When the volume of a chamber increases, the pressure decreases, and the fluid pours in. The diaphragm then moves down and forces the liquid out. Once the fluid has cleared the chamber, the diaphragm moves back into position, allowing more fluid to enter. This cycle continues while the pump is operating. This unique design means diaphragm pumps are able to move large volumes of liquid, making them great for refineries located near large oil sources. More wear-resistant than positive displacement pumps, diaphragm pumps have fewer moving parts or friction points, but they also suffer from “winks”. Winks are small gaps that slow the movement of fluid, which tends to happen over long distances. Petrochemical Pump - These pumps are used to process or refine chemicals during crude oil drilling and refining. Petrochemical pumps can be piston, diaphragm, mag drive, or another type of process or chemical pump. They can operate at high rates of flow and pressure within a refinery system. Petrochemical pumps prevent leaks, which also prevents hazardous environmental conditions. On the plus side, the simple design, ease of use, and compact size of the petrochemical pump provides the durability necessary to keep up with the demands of oil drilling. On the downside, these pumps are prone to overheating, cavitations, and internal corrosion. Each of these pumps offer an efficient solution for transporting chemicals and are used for a specific purpose. Regardless of whether they are used in upstream, midstream, or downstream processes, pumps provide the energy for fluids to flow from one place to another. DAE Pumps cont’d from page 15.

17 MAY 2021 WorldWide Drilling Resource® Top-of-the-World Tunnel Compiled by Carol C. Schimpf, Editorial Assistant, WorldWide Drilling Resource® Embedded under more than a mile of snow-covered rock at the top of the Himalayan Mountains in the eastern Pir Panjal Range, India, the Atal Tunnel, formerly called the Rohtang Tunnel, was opened to traffic in October 2020. This tunnel bypasses one of the world’s most treacherous roads, on which dozens of people died each year trying to cross through the high-altitude pass. In planning for decades and under construction for almost another decade, the Atal Tunnel promises to change the lives of isolated village residents for the better. The Kullu Valley is connected through the Rohtang Pass to the Lahaul and Spiti Valleys. At an altitude of 13,000 feet, the dangerous highway was open for only four months of the year due to unpredictable snowstorms and blizzards. The pass was named Rohtang, derived from the Persian and Farsi words Ruh and Tang, which combined mean “a pile of corpses”. Almost 20,000 people in the valleys were cut off from the rest of India, isolated from November to May, and forced to fly out on helicopters, weather permitting, if there were medical emergencies. Around 3500 to 4000 people were airlifted each year. Virender Sharma, the chief government official in Kyelang, the main town of the Lahaul Valley said, “In the winter, there is no light. No vegetables. No mail. Nothing to do in the evening. If there is an emergency, you are practically at the mercy of God.” Constructing an approximately five-mile tunnel in such a harsh, high-altitude environment was a daunting task. Complex topography and geologies, including peaks of 17,000 feet, presented enormous challenges to geological work, tunnelling, as well as mechanical and electrical installations. The Himalayas are full of geological surprises, including faults, folds, and shear zones, revealing their presence due to continuing tectonic movement. These features cannot be mapped out during the geological investigation prior to starting a project. They are hidden in such a way to make mapping impossible unless a project starts and real-time excavation begins. Not knowing exactly what kind of rock was inside the mountain, Thomas Riedel, a German contractor remarked, “That is where we will find problems.” Highly overburdened features of the material increased the problems, creating uncertainty in designing a particular support system and demanding a design-as-you-go methodology for the entire tunnel length. The New Austrian Tunneling Method (NATM), based on deformation monitoring data to evaluate quantity and quality of the support system, proved to be an appropriate tool for tunnelling in this environment. Once construction began, the NATM was driven to its limits. Crumbly-textured soils instead of blast rock, excess water ingress, high rock pressure with extreme deformations, and rapid changes in rock formations were major challenges to overcome. The tunnel was driven from two sides by the painstaking method of drilling and blasting, rather than using tunnel boring machines. Advanced techniques, including forepoling, lattice girders, pipe roofing, pregrouting, and chemical grouting, were applied. The horseshoe-shaped cross-section with an excavation diameter of more than 42 feet carries two lanes of vehicle traffic, two footpaths, and an emergency egress beneath the carriageway. During the nearly ten years of construction, Snowy Mountains Engineering Corporation (SMEC) provided detailed engineering and advisory services. Their innovation and technical skills allowed contractors to contend with poor rock-flowing conditions, avalanches, blizzards, and other challenges. Chief Engineer for the $230 million project, P.K. Mahajan, proudly commented on the tunnel completion as “an engineering marvel for the whole nation.” Designed to handle up to 3000 vehicles per day in any weather conditions at a maximum vehicular speed of nearly 50 miles per hour, the two-way traffic facilitates travel between the remote regions and the rest of India, effectively reducing travel distance by about 29 miles and travel times by up to four hours. The better transportation route is expected to improve the economy by allowing residents to sell their agricultural produce in towns and by opening the remote towns to more tourists. It will also provide a winter link to families and hometowns for those in remote regions. Atal Tunnel now provides safe, allweather travel in the northern regions of India, turning a once dangerous journey at the top of the world into a modernized pathway connecting a nation’s people.

18 MAY 2021 WorldWide Drilling Resource® Workhorses of the Cross River Rail Project Adapted from Information by the Government of Australia The Cross River Rail Project in Brisbane, Australia, is a huge undertaking, designed to unlock a public transport bottleneck caused by a single-rail river crossing. The 3.7-mile twin tunnels running under the Brisbane River and Brisbane CBD (Central Business District) will enable a smoother flow for the whole of southeast Queensland. Tunnelling on this massive scale presents complex engineering challenges, and the workhorses of the project are two machines, each suited to different types of work: roadheaders for excavation and tunnel boring machines (TBMs) for the actual tunnelling. Using a roadheader to break rock, excavation began in May 2020, with a 919-footlong cavern about 89 feet underground. Six roadheaders are being used to tunnel simultaneously. These are electrically powered tunnelling machines, which perform the finely-controlled digging needed for shallow tunnel, escape passage, and station cavern excavation. Each 126-ton roadheader is 72 feet long. A “pineapple,” the rotating excavating head with metal picks, cuts the rock. The roadheader is controlled by a cabin operator, while a cable spotter assists in safely maneuvering the machine. Excavating 66 tons of rock per hour, the roadheader’s cone will wear away more than 30 picks during an eight-hour shift and travel 3 to 16 feet in 24 hours. Two giant TBMs will dig the project’s twin tunnels after the roadheaders finish initial access. These machines are like huge underground factories, each supporting a 15-person crew and fully equipped with crew facilities, offices, and toilets. Each 541-foot-long TBM weighs 1488 tons. The cutterhead alone weighs 116.5 tons and measures 24 feet in diameter. There are 39 cutting disks, each exerting up to 35 tons of pressure. The two TBMs will each progress at a rate of 66 to 99 feet per day. As they bore, the machines will install massive 4.5-ton precast, interlocking, concrete segments to line the tunnels. Six concrete segments are needed to create just one ring. No gallop to the finish line, the project will, instead, be a slow, but steady, trot to completion. Expected total project completion is in 2024, with extensive safety testing to follow. Actual services are expected to commence in 2025. Roadheader TWO at Woolloongabba. Tunnel Boring Machine. DIR

19 MAY 2021 WorldWide Drilling Resource® The Un-Comfort Zone II by Robert Evans Wilson, Jr. Imposter Syndrome: When You Feel Like a Fraud These tips will help you with your fear of success. I heartily congratulated a friend on her job promotion. She replied, “What if they made a mistake? What if I’m not really qualified, and it’s the Peter Principle in effect - that I’ve risen to the level of my incompetence?” I told her she was totally qualified or they wouldn’t have given her the job. She then said she felt like a fraud. She was suffering from Imposter Syndrome. I understood how she felt, so I said, “I get it. I’ve been there. In my first year of speaking professionally, I was hired to present the keynote speech for a national association. It was extremely exciting, and exactly what I wanted, but the night before I was to go on stage, feelings of doubt emerged. And, like you, I felt like a fraud. Worse, I started to feel panicky. At that point, I knew I needed to shift my feelings back to positive ones. So, I started thinking about how I got to the point of being hired for that speech. I went to my bookcase and looked over the trophies I'd won for speaking contests in Toastmasters. I picked up each one and thought about the speech I gave to earn it. I recalled the smiling faces, the laughter, rousing applause, the standing ovation at the end, and the awarding of the trophy. Reliving those experiences restored my confidence, and I was able to convince myself that I was indeed worthy of the large fee I was going to be paid, and that everyone would love the speech I was going to give.” Add Up Your Achievements “That’s great, but I don’t have any trophies,” my friend admitted. “But, you do have accomplishments. Make a list of them, big and small. I keep a journal of accomplishments and achievements so I don’t forget them - especially the little ones because they all add up. Then when those negative feelings start up, and you start to doubt your competence, go back and read about all your successes for a quick attitude boost.” According to Wikipedia, “Impostor Syndrome is a psychological pattern in which an individual doubts their skills, talents, or accomplishments and has a persistent internalized fear of being exposed as a fraud." It is an irrational fear that someone will discover your success is unearned. Imposter Syndrome is a term derived from Imposter Phenomenon which was coined by researchers Dr. Pauline R. Clance and Dr. Suzanne A. Imes, who discovered some high-achieving women lacked the ability to acknowledge their accomplishments and instead credited them to luck or people overestimating their intelligence. It was later discovered that both men and women suffer from Imposter Syndrome in equal numbers. To a degree, these feelings are natural. As Orrin Woodward, a leadership and management expert observed, “Most people overestimate others' talents and underestimate their own.” Perfectionism is the Problem Imposter Syndrome, for many people, comes from perfectionism. Perfectionism is all about fear of failure, or fear of not performing well enough. It has its roots in criticism - usually from parents or other authority figures in your youth. In their book, Perfectionism: What's Bad About Being Too Good?, Miriam Adderholdt and Jan Goldberg cite family pressure as one of the main causes of perfectionism, and note it often develops during childhood. You can overcome perfectionism if you can teach yourself that it is okay to do an adequate job on a task instead of a perfect one. If you are a perfectionist, you need to accept that perfect is impossible. The trick is to allow some imperfection into your life a little at a time so you can get comfortable with it. Like any other addiction, you must wean yourself. Another way to deal with Imposter Syndrome is to live each day mindfully. By focusing only on what you have to accomplish each day helps keep your mind off the bigger picture, which can be overwhelming. Living in the now prevents the anxiety that comes from living in the future. Keep a Journal of Your Accomplishments If you suffer from Imposter Syndrome, or any feelings of inadequacy, I recommend you keep a journal of your accomplishments to refer to whenever those feelings start to emerge. Record in detail the achievement - the what, when, why, where, and how. What did it mean? Why did you do it? What difference did it make? How did it make you feel? Who was there? Who congratulated you? The more specifics you provide, the easier it will be to relive the experience and boost your self-confidence. Start today by listing your past triumphs; then continue to add to the list as you remember more of them and acquire new ones. And whenever those feelings of fraud come along, open your journal and read! Robert Robert is an innovation/change speaker, author, and consultant.
