一个社会的成功主要应通过其成员所享有的实质性自由来评估。

未来属于那些能够明智利用能源的人。

快乐的最好方法是感恩。

I hope that in this year to come, you make mistakes. Because if you are making mistakes, then you are making new things, trying new things, learning, living, pushing yourself, changing yourself, changing your world. You're doing things you've never done before, and more importantly, you're doing something.

The course of human life is not determined by drives or environment alone, but by creative self-direction as well.

变化是不可避免的，你如何应对决定了你的成功。

心灵不是一种事物，而是一个过程。
