Roosevelt's "The Man in the Arena" 竞技场中的人

"It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat."

“荣誉不属于在一旁指指点点的人，不属于那些谈笑强者跌倒或者哪里可以做得更好的人。
荣誉属于真正在竞技场中努力，那些脸庞沾满灰尘、汗水和鲜血，那些勇敢奋斗，屡败屡战的人。因为任何努力都会有错误或缺点；荣誉属于投身于有意义的事业，属于敢于追求伟大梦想，最终取得伟大成就或者虽败犹荣的人。这样，竞技场中的人，他的位置，将永远超越那些冷漠胆小而不知胜败的人。”
