The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
如果你需要一只援助之手,你可以在自己的任何一只手臂下找到;随着年龄的增长,你会发现你有两只手,一只用来帮助自己,另一只用来帮助别人。
永远不要让成功冲昏头脑,也不要让失败打击你的信心。
Life is about creating yourself.
没有一个明智的飞行员会忘记使用他的清单,无论他的才能和经验有多么出色。
