“ People who are unable to motivate themselves must be content with mediocrity, no matter how impressive their other talents. 那些不能激励自己的人必须满足于平庸,不管他们的其他才能有多出众。 Andrew Carnegie 安德鲁·卡内基
“ The wise man does not expose himself needlessly to danger, since there are few things for which he cares sufficiently; but he is willing, in great crises, to give even his life - knowing that under certain conditions it is not worthwhile to live. 明智的人不会把自己不必要地暴露在危险之中,因为很少有事情是他足够关心的;但他愿意在重大危机中献出自己的生命——他知道,在某些情况下,活着是不值得的。 Aristotle 亚里士多德
