Learning to be an adult

Becoming an adult for me is not interesting because for me children is more fun than become an adult.Why I said like that?When I was children I feel very happy and I can play anythings I want with my friends.Besides that,I also feel no tension and no pressure.
When my age increasing,I feel no more enjoyful like I before.This is because I have go to school and I have many homework.Then I do not have so much time to enjoy with my friends anymore.I need to spend my time to do my homework.
Now I studying in university and I feel that I become different people,I think that I was become an adult like my sister and my brother.I have to be an independent person.In my opinion,becoming an adult was not very interesting because I have many works to do.I have to study in university and then I will get my job and I must do my job for all my life.But I know that it is normal process for a people to become an adult.I must to accept that and I must realize that now I had become an adult.I must be a good person for my future life.
