How can I win?

Some people say that the world is harsh. We can survive, when we compete with many people and win them. If we can not bit them, we will become a loser. "How can I get more good grade than others?" We thought about this problem. Even if we are still, this agony is very important for our lives. Life is not like sports because sports decide winner and loser for one play.However, I believer that there is secret of victory for our lives. For example, two men like one girl. One day three people meet in the street. Two men might stare each other? If one man suddenly say bad word to another person, another man and the girl feel bad. In fact the girl will choose the kind man. It means when we live in our lives, we must control in our mind widely.
