When can we happy?

　Actually when I was a high school student,I really wanted to be a university, because studying was a very difficult job, and the College Scholastic Ability Test was a burden to me. I groaned under a heavy burden, so I really want to be free from my burden. Even if I become a university student, I should study very hard, and have many assignments. Not only that, but I take the responsibility for my action. Now I think it is better than now to have been a high school student. if we always complain of our life, when can we become happy? I think to be happy we should be thankful for the present existing situation, even if it is very hard to overcome. Many people think when they are young, they really want to be adults, and if they are to be adults, they will be happy, and when they are adults, they think when they were children, they were happy.it is better than now to have been children.I think life isn't long, so it isn't enough to be happy, love, thankful for others. What I want to say is to let's live our life more precious!
