精神工作导致的疲劳不是因为工作的数量，而是因为工作的质量。

我不是一个喜欢传统的人。

Courage doesn’t mean you don’t get afraid. Courage means you don’t let fear stop you.

There's not a day goes by I don't feel regret. Not because I'm in here, or because you think I should. I look back on the way I was then. Then a young, stupid kid who committed that terrible crime. I want to talk to him. I want to try and talk some sense to him, tell him the way things are. But I can't. That kid's long gone and this old man is all that's left. I got to live with that. Rehabilitated? It's just a bullshit word. So you go on and stamp your form, sonny, and stop wasting my time.Because to tell you the truth, I don't give a shit.

Science is a powerful tool for humanity to understand and transform the world.
