解释：时机未到，就不能勉强行事；行事不探求事理，就不可能达到成功。

今天种下的每一棵树都是我们永远不会见到的后代的遗产。

写作的行为是一种爱的行为。

The best architecture is timeless.

写作就是找到一个声音来倾听你内心的声音。

I’m not perfect, but I’m always me.

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.

过去不是我们抛在身后的东西；它是我们内心携带的东西，塑造着我们的现在和未来。

我不相信过度分散投资。我更喜欢集中在几个好主意上。
