Morality binds and blinds. It binds us into ideological teams that fight each other as though the fate of the world depended on our side winning each battle. It blinds us to the fact that each team is composed of good people who have something important to say.

You have to be able to admit when you're wrong and move on.

人生是由小小的幸福积累而成的。

定理不是偶然发现的。

成功不是终点，失败也不是致命的：重要的是继续前进的勇气。
