Leadership is about making tough decisions with compassion.

"Writing is an act of courage—you have to be willing to expose your deepest thoughts."

It's not whether you get knocked down, it's whether you get up.

The only service a friend can really render is to keep up your courage by holding up to you a mirror in which you can see a noble image of yourself.

人们不应该研究这样的问题，应该把它们留给哲学家。

最重要的是享受你的生活——快乐——这才是最重要的。
