"Mathematics is not a spectator sport."

Happiness is beneficial for the body, but it is grief that develops the powers of the mind.

人生冇如果，只有结果同后果。

The art of competing, I’d learned from track, was the art of forgetting, and I now reminded myself of that fact. You must forget your limits. You must forget your doubts, your pain, your past.

Life is short. Stunt hard.

没有人值得你流泪，值得让你这么做的人不会让你哭泣。
