首要且最伟大的胜利是战胜自己。

"I must say a word about fear. It is life's only true opponent. Only fear can defeat life."

The true measure of success is not just profit, but the positive impact we leave behind.

I’m positive that in 100 years much of what I take to be true today will be proved to be wrong， maybe even embarrassingly wrong， and I try really hard to identify what it is that I am wrong about today.

每个革命者的责任就是进行革命。
