过去总是紧张的，未来是完美的。

I'm grateful for every moment, every experience.

理解自然的复杂性是终极挑战。

成功的真正标准是你对他人产生的积极影响。

If you don’t go after what you want, you’ll never have it.

Is there any relief from some of thesepressures that I've been outlining? I think there is. I just want to turn to afew of them. Let's take meritocracy. This idea that everybody deserves to getwhere they get to, I think it's a crazy idea, completely crazy. I will support any politician of Left and Right, with any halfway-decent meritocratic idea; I am a meritocrat in that sense. But I think it's insane to believe that we will ever make a society that is genuinely meritocratic; it's an impossible dream.

最重要的教育原则是不要爱惜时间，要浪费时间。

Success is a journey, not a destination. The doing is often more important than the outcome.

I don't know anyone who needs a hug more than I do.
