What do you want to be when you grow up? Most parents and teachers often ask us this question. Some want to be an engineer, some want to be a pianist, and some want to be a scientist. For me, I want to be a violinist when I grow up. However, my parents want me to be a doctor to work in a hospital. I really don't like it.One day, I talked to my parents about my personal thought and they agreed at last. I also make a promise to them. I wrote it on a piece of paper. It said : First I am going to study harder than before and do my schoolwork more carefully. Then I am going to make weekly plans. Finally I am going to exercise every day to keep health.
