The secret of change is to focus all of your energy not on fighting the old, but on building the new.

The best preparation for tomorrow is doing your best today.

I have lived with the prospect of an early death for the last 49 years. I'm not afraid of death, but I'm in no hurry to die. I have so much I want to do first.

到最后，我们只会后悔没有抓住的机会。

What I am is good enough, if I would only be it openly.
