I turned in my third-year midterm exams with only my name written and all subjects blank. At the time, I would leave home but not go to school. It was a dark time in high school, constantly sending out SOS signals and pleading for help from those around me. I was in a bad state of mind, constantly running out of attendance days in both my second and third years of high school. Immediately after my third-year midterm exams, my parents took me to a private tutoring school called Tokyo Individualized Instruction Academy. There, I learned English, math, and physics. The instructors were all current university students. My English teacher was Professor Hasegawa from the University of Tokyo; my math teachers were Professor Maruyama from Chiba University and Professor Otawa from the Faculty of Pharmaceutical Sciences at Tokyo University of Science; and my physics teachers were Professor Okamura from the Faculty of Engineering at Tokyo University of Science and Professor Takahashi from the Faculty of Science at Gakushuin University. As a third-year high school student, having the opportunity to speak with instructors who were currently university students was a great benefit. In particular, influenced by Professor Otawa, who is a student at Tokyo University of the Arts' Faculty of Pharmacy, I began to aim for Tokyo University of the Arts' Faculty of Science and Engineering around summer. I had studied neither math nor physics at all in my first and second years of high school, so math held me back. However, I spent time on each unit and on regular exam-level questions, such as accurately drawing differential graphs, calculating recurrence relations, and drawing vector perpendiculars, and I made up for my lack of math with my physics and English, and was accepted into Tokyo University of the Arts' Faculty of Science and Engineering while still in high school. Upon entering university, I started working part-time as an instructor at Tokyo Individualized Guidance Academy (TKG). While I really enjoyed my work, I was unable to attend Tokyo University of the Arts as I had in high school, and decided to drop out after six months. After consulting with senior instructors at my part-time job, I decided to revisit my dream of becoming an elementary school teacher, a dream I had always had from kindergarten through junior high school. I talked to my parents, and they convinced me to quit Rikkyo University of Science and Technology in September of my first year of university and aim for Tokyo Gakugei University. For the next year and a half, I worked part-time as a lecturer at TKG while mostly studying for entrance exams at home. In the summer of my second year of retaking the entrance exam, I signed up for and took just one summer course at Kawaijuku. That was the first time I took a cram school class. It was taught by Professor Daikichi, who I think is now at Toshin. Later, in the second semester, I heard that Professor Otawa, the aforementioned TKG lecturer from Rikkyo University's Faculty of Pharmacy, had taken Professor Ogino's classes at Yoyogi Seminar, the same school he attended when he was taking entrance exams. So, using the money I earned from my part-time job at TKG, I took Professor Ogino's single-subject course at Yoyogi Seminar called "Science Mathematics to the Sky." I think it was once a week, on Fridays from 6pm for 90 minutes, but by the time I entered Tokyo Gakugei University, my dream for the future had changed from elementary school teacher to cram school instructor. The main message I want to convey here is that the moment you encounter something you want to become, you'll know it. And I also felt that I could do it. It may be conceited, but I clearly felt that if I had the knowledge, I could teach it too. I thought that the message wouldn't be conveyed unless I described the process I took to get there, so I wrote this lengthy article. I hope it's helpful. You'll probably never find what you truly, truly want to be unless you keep searching desperately for it. Also, even if you do find it, if you don't acquire the skills, knowledge, and abilities before entering society, that is, while you're a university student, it will actually be too late once you start working, because you'll have so little free time. In other words, if you don't currently have something that will make you a living, you should recognize that you need to find it while you're a university student and hone it to a level comparable to that of a professional. Otherwise, you'll just end up drifting along with the flow. Finally, this time I've written about my own experiences until I found what I wanted to be, but when you encounter it, you'll definitely know it and probably feel, "I can do this too." Also, I only talked about how I encountered it and did not wr...
