"The world is a stage, but the play is badly cast."

You manage things; you lead people.

任意能让你脱离现实的避风港，都是艺术。

Your smarts will come in handy because you will travel in a land of marvels. We humans -- plodding as we are -- will astonish ourselves. We'll invent ways to generate clean energy and a lot of it. Atom by atom， we'll assemble tiny machines that will enter cell walls and make repairs. This month comes the extraordinary but also inevitable news that we've synthesized life. In the coming years， we'll not only synthesize it， but we'll engineer it to specifications. I believe you'll even see us understand the human brain. Jules Verne， Mark Twain， Galileo， Newton -- all the curious from the ages would have wanted to be alive most of all right now. As a civilization， we will have so many gifts， just as you as individuals have so many individual gifts as you sit before me.

什么是言论自由？没有冒犯的自由，言论自由就不复存在。

To live is the rarest thing in the world. Most people exist, that is all.

我已做了所有的打算，其余就交给上帝了。
