At its core, I don't view Facebook as a social network. I think it could become the driver's license of the Internet. And beyond that, it can become the pipes and the plumbing upon what most of the Internet is built. I think it's very well positioned.

That's precisely the question everyone should be asking-why the hell not? - Why not you, why not now.

To do the impossible, you need to ignore the popular.

Slow down and remember this: Most things make no difference. Being busy is a form of mental laziness-lazy thinking and indiscriminate action.

If you don't have time, the truth is, you don't have priorities. Think harder; don't work harder.

I work hard, but in spurts.

I do not equate productivity to happiness. For most people, happiness in life is a massive amount of achievement plus a massive amount of appreciation. And you need both of those things.
