The only way to do great work is to love what you do.

The difference between a good business and a bad business is that good businesses throw up one easy decision after another. The bad businesses throw up painful decisions time after time.

Pain is not just a sensation; it's a complex biological response that tells us something is wrong.

历史不仅仅是事实——它是人类的心跳。

数学的美在于它既精确又富有创造性。

真正的进步发生在我们敢于质疑现状之时。

我们要做的不是跟随，而是引领。

我不相信失败，因为我不相信放弃。
