When I was a university student, I used to play the Touhou series. These are a Japanese, somewhat famous shoot-'em-up series made by an amateur game creator, ZUN. This game is known as a game to avoid an enormous number of bullets rather than shooting enemies. And, because the bullets are too many, it is usually difficult to beat all the stages on our first try. It requires us to have enough practice. In short, we have to memorize all the patterns of barrage fire in all the stages by trying many, many times. I used to be pleased every time I beat a stage. It means that my practice was effective, and practice is the only way to become good at something. And I finally understood that it can be said to almost everything. Because I'm an ordinary person and not a genius, I have to practice for everything if I want to be good at it. I would appreciate it if you corrected my post!
