不断思考你如何能做得更好，并不断质疑自己。

For the eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace.

预测未来的最好方式就是创造未来。

Leadership is about making the tough decisions and standing by them.

译文：身体没有经历过饥饿和寒冷，就是上天对我最大的恩赐；学业没有进步，我用什么脸面面对苍天呢。赏析：人要懂得感恩知足，没有病痛折磨，没有挨冻受饿，就是人生最大的幸福。学业毫无进步，说明我们懈怠了，不读书，我们就不能获得先贤的思想精髓。

唯一的旅程是内心的旅程。

One never notices what has been done; one can only see what remains to be done.
