To be free is not merely to cast off one's chains, but to live in a way that respects and enhances the freedom of others.

Mental life is fundamentally about adjustment to environment.

Everything negative — pressure, challenges — is all an opportunity for me to rise.

当你停止追求进步的那一刻，就是你开始死亡的那一刻。

保持饥饿，保持愚蠢。
