There have a famous saying:no pain ,no gain. But I doubt the famous whether right. Truly , sometime,The success come from pain, but I believe that the happiness can let us more success. Have some scientific research point out , in same condition case, The happiness person more success than the pain person. There have some reason can explain this case.

  Even for stay a job, we must keep learn and grow, for learn and grow , we must undergo some fail. Those successful person in history, they are undergo mach fail time person too. Edison, he registered many patents in his life, it include electric lamp,answering machine,and telegraph. He was said with pride: He was stared fail to toward success. When Edison making his patent , have someone admonish him that he had been fail for ten thousand times . Edison replied him that I don`t fail , I just found ten thousand species of no right way.

  Michael Jordan, He is great basketball player. Have someone said that he is a gad in basketball history. But he said he is a average person, he said :in my basketball life , I missed shot for over nine thousand times, I lose match for over three hundred times .have twenty six times , I believed can hold down match, but in last time shot out the important ball, it was missed , for me, the match was lose . my life is unceasing fail ,fail , fail again, this is my success reason.

Have a man , he was lose his job in twenty two years. One year later, He wanted join political circle, he went to run for the state legislature, then he was be defeat. Later , he was join business circles , then he was also came to nothing. In his twenty seven years, he got anxiety disorder, his mind was broken down . but he stood again, and in his thirty four years, he went to run for congressman, but he was be defeat again. Five years later, the same hing was happened , he went to run for congressman , be defeat again. Obviously, He don`t give up for fail, even set a more high goal than before. In his forty years , he had endured many years fail later, he went to run for senator, but be defeat again. Then , two years later, The man , Abra-ham Lincoln became president of American.

 This some stories of great people, but their stories model are same with another people who are got many successful people`s stories, they are both started fail to towards success. Even thought fail not must to towards success, but if lack the experience of fail, it must keep away from success. Those are people who realize the fail and success are exist together is those can learn ,grow from fail , and in last become successful people. Only accept fail, then can learn from fail.
