I am heartily rejoiced that my term is so near its close.

If you do not tell the truth about yourself you cannot tell it about other people.

Let the world change you and you can change the world.

活得足够长以超越你可能获得的任何怨恨感是值得的。

乐观是一种工具，你可以用它来实现你为自己设定的目标。

History will be kind to me for I intend to write it.

I think the most important thing is to be honest and truthful with what you say and what you do.

“科学的美丽在于它让我们以一种既深刻又实用的方式理解世界。”
