Mental life is a continuous adjustment to circumstances.

我认为最重要的是不要满足于现状。

Knowing is not enough, we must apply. Willing is not enough, we must do.

The only person you should try to be better than is the person you were yesterday.

你要记住，在敢于担当培养一个人的任务以前，自己就必须要造就一个人，自己就必须是一个值得推崇的模范。

心智是一套信息处理机器，它们由自然选择设计来解决我们狩猎采集祖先面临的适应性问题。
