The most regrettable time period was after the college entrance examination. When I knew my grades, I filled out the application form and just filled in one type. As a result, I was transferred to a major that I didn't like. For a moment, I felt that the sky was falling. I happened to take the third subject without thinking about it and just failed. This seems to be the first time I realize that not everything will go according to my established route and goals. A slight mistake can be a huge difference. It was just one step, but it was two completely different paths of destiny. After being confused, I took many wrong paths and made many wrong choices, which made people around me sad.
