"The greatest battles are fought within the silent chambers of our own hearts."

Success is not final, failure is not fatal: it is the courage to continue that counts.

To succeed, you need to create value for others, and that requires understanding what others value.

The past is not dead; it is not even past.

经验只是我们给错误起的名字。

理论上，理论和实践之间没有区别。但实际上，是有区别的。
