Anxiety, many students have been troubled by this. After entering the school, they will become very unhappy. In the past, they thought that they would become excellent if they studied for 8 hours every day, but when they found that people around them studied 10 hour or 12 hour every day, they felt very anxious. Although I said I didn't regress, everyone around me is making progress. By contrast, I'm going backwards.
If you work hard, you should constantly strive to improve yourself after entering the university, otherwise you will be eliminated. Therefore, although college students have not yet entered the society, they have been hurt by involution. When everyone around you is improving, if you don't move, you will be eliminated. This phenomenon is unwilling to happen, so everyone is forced to work hard.
