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.

理论上存在一种完美的幸福可能性：相信自身内不可摧毁的元素，而不必努力追求它。

译文：要有所获取，就一定要有所舍弃，要有所禁止，就一定要有所宽容。赏析：人生没有完美的事情，世间的所有好事不可能都让我们占完，总是有舍才有取，有失才有得。禁止就是不可为，宽容就是我们对待别人要圆滑。

I try to capture the flow of time with gunpowder. 我试图用火药捕捉时间的流动。

我是个斗士。我相信积极的一面。我相信努力工作。

民主的力量在于尊重差异和多样性。
