How did you choose your industry?

Primary and secondary school training industry. I struggled for a long time in senior three, but I decided not to go out to work. There are almost no jobs for the undergraduate counterparts in the physics department, and after all, they gave up graduate school because they didn't want to do physics anymore. The initial reason for looking for this business is that I am sure I can do it well. My previous good grades in school can give me an innate advantage in this business. After really starting to do it, the "like to play with children" accumulated since childhood broke out. In addition, I also like to think about things like "how did this happen", so the more I do it, the more I like it.
