Can Mechanical Aptitude Books Improve Job Performance?

Mom is very biased. Every night, she will pour me a glass of milk before bedtime, simply because my grades are the best. My twin sister, Melody York, and my younger brother, Jason York, have never received this treatment before. On the night before my college entrance exam, Mom brings me a glass of milk before my bedtime as usual. But the next day, I end up collapsing in the exam venue even though I've always been healthy. Because of that, I miss out on the college entrance exam, causing me to fail. Meanwhile, Melody, whose grades have always been terrible, miraculously gets into an outstanding university. Mom consoles me, telling me that it's fine to just repeat the senior year. Every night, she prepares the same glass of milk for me as usual. Before the second college entrance exam, my cousin, Annie Wood, is staying over at my place temporarily. She wants to have a taste of my nighttime milk, only to get berated by Mom for being shameless. But halfway through the exam, I suffer from an intense stomachache all of a sudden. After that, I get sent to the hospital for emergency treatment. That year, I end up failing the exam again. But Annie, who comes from a vocational high school, gets into a pretty good university thanks to her scores. The entire family is elated, to say the least. But the fact that I have to repeat my senior year for the third time makes me the butt of everyone's jokes. I don't understand why all sorts of health problems will plague my body when it's time for my college entrance exam. When I'm taking the exam for the third time, I tell myself that this is my final chance, so I mustn't slack off no matter what. Three days before the exam, the only food I've ingested is the food offered by the school's cafeteria, just in case I run into more health problems on the day of the exam. But on the night before the exam, Mom brings me yet another glass of milk before bedtime.

I, Lilian Newton, am the top luxury goods repair specialist. 90 percent of the store's revenue comes from me. Three years on the job, I turn a little shop that nearly goes bankrupt into a nationwide chain. Just because I am two minutes late to work, the new manager locks the front door and plans to take the staff on a trip. I ask her why I was not informed. She scoffs and says, "The capable should do more work. We are going on a trip. You stay behind to work overtime. If you can't handle it, then get lost!" I laugh in exasperation and call my husband right away. "I hear you're planning to fire me. Is that it?"

When the SAT scores are out, I've scored 400 out of 1600. That's because I never wrote anything on my exam papers. My mom goes crazy, whereas my younger sister, Melinda Bolton, bursts into tears. But I just laugh at them instead. In my previous life, Melinda had formed a pact with the score-swapping system. That was how she swapped our SAT scores. She became the top scorer that all prestigious universities fought to recruit. I, the valedictorian of my year, not only got into a trade school, but I also got expelled from my previous high school. Melinda had the gall to comfort me. "Didn't you call yourself a genius, Melissa? Trade schools are very popular right now. In the future, you'll secure a job at a factory out there!" In this life, I spend my exam hours sleeping in my seat the whole time. Melinda wants to swap her scores, right? Then, let's do it properly!

My younger sister, Joey Crawford, and I have taken the exam 20 times in a row. Yet, our answer sheet shows the exact same answers every time. No matter how fast I complete the exam, Joey is able to turn in her paper one second before me. My homeroom teacher, Mr. Harris, has spoken with me three times regarding this matter. At the same time, I receive my first warning for cheating on the exams. Whenever my classmates see me, they say to me, "Hey, cheater! You got busted this time, huh?" The thing is, I've never even touched Joey's paper. How can our answers be exactly the same? During the college entrance exam, I suddenly awaken to the ability to see the live comments dangling in midair. "The female lead is the chosen one! It must feel amazing to have awakened the mind-reading ability and all!" "She relies on reading the side character's mind just to obtain all the answers. So what if the side character excels in her studies? Her role is to become the female lead's stepping stone to success!" It turns out that Joey has been stealing my answers by reading my mind this whole time. As I flip the exam papers over, I start singing the alphabet song mentally. "A-B-C-D-E-F-G…"

My father was a senior HR executive. He used KPIs to define my life. "Rank top ten in your grade, and I'll give you a B, with a bonus of 250 dollars. "Place in a state-level competition, and you'll get an A, with a bonus of 500. "If your SAT score hits Ivy-level, I'll give you an S+ and a 5,000-dollar year-end bonus." I studied as if my life depended on it, and in the end, I got the acceptance letter. My father slapped a contract down in front of me instead. "Congratulations on onboarding into the next phase. Starting today, your allowance will be structured as base salary plus performance plus attendance bonus. "Base pay is 250 dollars a month, enough to keep you from starving. "To prepare you for a high-pressure work environment, I’ll conduct random inspections. Fail, and your pay gets docked." When I ran a 104°F fever, he cut my attendance bonus, saying my physical resilience didn't meet standards. When I forgot to submit a weekly report because I was buried in schoolwork, he froze all my money. To stay alive, I went behind his back and sold blood at the hospital. At the end of the semester, I held my transcript and scholarship certificate, thinking I had finally earned the highest rating. But my father looked at me without a trace of warmth. "Your S+ bonus has been reallocated. The company decided to invest it in your brother, Harry. He has more potential." I looked at the 100-dollar "consolation prize" he handed me and laughed. So in his company, I didn't even qualify as an "outstanding employee."

I had been managing the company’s warehouse software for five years. Then the new manager came to me out of the blue, saying I didn’t understand frontline operations and that I was being fired. Looking at the five-thousand-dollar severance, I just nodded. “Fine.” He patted my shoulder after seeing me so compliant and started lecturing. “Young people should be out on the line, moving boxes! What’s the use of sitting in the office staring at data every day? “We’re a logistics company. Strength is what matters, not a tech geek like you!” I glanced at the high-end gaming computer in his office and obediently replied, “Yes, Mr. Fuller. Lesson received.” Maybe I had been too comfortable these past few years, and he thought I was dispensable. So, I handed over my ID badge and casually deleted all my personal login keys from my computer. Little did he know that the entire warehouse logistics, inventory management, and route planning software had been coded by me. I had let the company use it for free simply because the place was close to home and the work was easy. Now that I was gone, the system running on my personal cloud server was naturally inaccessible. Tens of thousands of items in the warehouse ground to a halt. As for any commercial software that could replace my system, a year’s subscription would cost exactly one thousand times my severance.
