The night is a time of truth, when masks fall and souls are laid bare.

别把你的旅程与他人比较，每个人都有属于自己的路。

你必须忠于自己。足够坚强才能忠于自己。足够勇敢才能足够坚强地忠于自己。足够健康才能足够勇敢地足够坚强地从真实的自我中塑造自己。

Sustainability isn't a buzzword—it's a responsibility we owe to future generations.

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.

大多数人发现他们从未后悔的事情只是他们的错误，但发现时已经太晚了。
