if you think you are beaten, you are.
if you think you dare not, you don't!
if you want to win, but think you can't, it's almost a cinch you won't
if you think you'll lose, you're lost; for out in the world we find success begins with a fellow's will.
it's all in state of the mind.
life's battles don't always go to the stronger and faster man.
but sooner or later the man who wins is the man who thinks he can.
翻译：
如果你觉得你被打到了，你就真的失败了。如果你觉得你不敢，你就真怂了。如果你想赢了，但自己都不敢相信能赢，那么十有八九你赢不了。如果你觉得要输，那么你已经输了；因为我们发现人世间的成功都开始于人的意愿。一切在于心态。生活这场战斗，不一定都是强者胜。胜利属于那些认为自己能赢的人。
