"I'm here to make history."

翻译：事物发展到了极点，就要发生变化，发生变化，才会使事物的发展不受阻塞，事物才能不断的发展。

I want to liberate America from fear. I want people to be afraid of the things that are really scary, like war and famine, not their neighbor because he has a different religion.

I love what I do, and I'm passionate about it.

提醒自己快死了，是我在人生中面临重大决定时，所用过最重要的方法。因为几乎每件事－所有外界期望、所有的名声、所有对困窘或失败的恐惧－在面对死亡时，都消失了，只有最真实重要的东西才会留下。

Psychology must be a science of life, not just of the laboratory.

当你停止相信的那一刻，你就已经失败了。
