The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.
知识最大的敌人不是无知，而是知识的幻觉。
The reality is: sometimes you lose. And you're never too good to lose. You're never too big to lose. You're never too smart to lose. It happens.
生活是10%发生在你身上的事，90%是你如何应对它。
知识的最大敌人不是无知，而是知识的幻觉。
The things you do in your 20s will shape your future.
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.
衡量一个人的真正标准是他如何对待那些对他毫无益处的人。
