What did people say in topic " who am I"?

      The first day, teacher lets students to decribe themselves, he lets students write something about this topic. The students shows their own ideas about this topic, there are many different definitions about this. Most of students define it from their age, name and goal. In my opinion, i think it depends on an attitude. If you have a good expectation on yourself, you will control yourself all the time. And you will have more confidence.
