我对自己是谁、做什么非常有信心。

The best time to plant a tree was 20 years ago; the second best time is now.

The boundary between inside and outside is not a line, but a gradient.

The biggest risk is not taking any risk. In a world that's changing really quickly, the only strategy that is guaranteed to fail is not taking risks.

人的思想是了不起的，只要专注于某一项事业，就一定会做出使自己感到吃惊的成绩来。

世界因你的榜样而改变，而不是因你的观点。

我不怕死，我只是不想在我死的时候在场。
