Every thought serves some biological purpose.

The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

人是万物的尺度：对于存在的事物，它们存在；对于不存在的事物，它们不存在。

我喜欢竞争。我喜欢比赛。我喜欢挑战世界上最优秀的球员。

The lack of money is the root of all evil.

我唯一拥有的就是我的声音和我的故事。
