Leadership is about making the tough decisions and standing by them, even when they're unpopular.

The world may be cruel, but it is also beautiful.

Mathematics is not a spectator sport.

I don't care what you say about me as long as it's not true.

唯一的正义就是遵循灵魂真诚的直觉，无论是愤怒还是温柔。

没有事情的时候，需要照管这颗心，小心谨慎，好像有事一样；有了事情的时候，却要放下这颗心，泰然自得，好像没事一样。没有事情能像有事一样提防，才可以平息意想不到的变故；有了事情能像无事一样镇定，才能消除事件过程中的危机。

If you have no enemies, you're dead.
