We students often feel stressed because we have too many homework to do every day. We are such busy studying all day that we don't have free time to do what we are interested. So we always felt very tired. What should we do to relax ourselves then?
First doing sports with some of our classmate is the best way to relax ourselves. It is also good for our healthy. Second, we can also listen to music during the breaks. Third, when we feel tired, go to the movies with our parents on weekends is another good choice, which will help us build a much more closer relationship with them. In short, they should spend a little time on relaxed activities each day.
