Why some people can be success while some people are always failed? Compare with both of them, we can find some different characteristics from them. So what is the most important characteristic that a person can have to be successful in life? I think hard spirit is the most important characteristic a successful person has. Maybe some people don’t agree with me. I gave the reason why I support this is based on the following aspects.
 At the first place, there are many difficulties on the way be success. If a person gives up when he meets difficulties, how can he get the final success? He will ever be a loser whatever he own what other characteristics. For example, one of my classmates Jack who is very intelligent. He always understands what teachers tell us immediately and learn new things quickly. But he is not a successful people, he often retreats when he meets difficult. I remember once we took part in a computer program game. It is very difficulty for us. He gave up when he can not know it with out research it. So, in the end, he was one who got the least score. And crossing 5 day and night, I completed 8 difficult subjects and won the game. From Jack, we can consider that hard is the base of other characteristics a successful person should have.
Further more, hard spirit can make people who is not bright become intelligent. Why? Because when people are not studying, the not bright people are studying. So he get the knowledge bright people not. Maybe the not bright people understand a problem more slowly than smart people, but he can spend more time to understand the problem. He spend one more hour to understand a problem which a bright people has known, if he spend another one hour to study another problem which other people did not study, then he can become more intelligent than other people. Take Yoming an example, he become a NBA player because of his working hard. So if you have the spirit of hard spirit, it means you have the high intelligence.
 However, other characteristics are also important for a person be success. A smart person can spend other time on other things. And he can accept the new things easily. For example, Einstein is very bright as know, he invented many great things witch had changed people's life. But he worked also hard; he always worked for his invention without eating and sleeping day and night.
Above of all. I firmly believe hard spirit is the most important characteristic for people to be success, though other characteristics are also not shorted for. Only one people own the hard spirit first, can he be success with other characteristics.
