I have ever seen many people who study very hard became insane. I think it because they have no time to relax. They are always strict with their lives in spite of they are clever. No different from us, many students must study hard too because they would like to admit in the university including me. I am usually stressed when I can’t do homework, don’t understand the lessons or have a surprise quiz. All of these destroy my body. Since I am too serious with my works, I often have a headache and have a bad mood. However, I think I am stressed due to I don’t attempt enough, so I should study hard and enjoy with it in order to don’t become insane.
