保持渴望，保持年轻。

And I hope you will come back here to Harvard 30 years from now and reflect on what you have done with your talent and your energy. I hope you will judge yourselves not on your professional accomplishments alone, but also on how well you have addressed the world's deepest inequities…on how well you treated people a world away who have nothing in common with you but their humanity.

The lack of money is the root of all evil.

我们不需要魔法来改变世界，我们内心已经拥有所需的力量。

理解自身的阴暗，是对付他人阴暗一面的最好方法。

有什么方法可以解决刚才提到的这些焦虑呢？是有的。我想提出几项，先说“功绩主义”，也就是相信每个人的地位忠实呈现他的能力，我认为这种想法太疯狂了，我可以支持所有相信这个想法的，无论是左倾还是右倾的政治家，我同样相信功绩主义，但我认为一个完全彻底以能力取决地位的社会，是个不可能的梦想。

The only thing I can control is my effort and my attitude.
