Gray hats are the ones who think they're doing good, but they're not. You learn that when the FBI shows up on your doorstep.

You just keep pushing yourself harder and harder to achieve more and more - I don't think it's ever quite as glamorous as it appears on the outside.

I've been doing a hybrid of investing and entrepreneurship, which I think initially I wasn't set out to do. But I realized it fit my personality.

There is no simple answer to what I think.

You actually don't want people thinking your product is cool, because then you're a fad.

I think Facebook's biggest problem is the glut of information that Facebook's power users are overwhelmed with.

It’s not cool. I think being a wealthy member of the establishment is the antithesis of cool. Being a countercultural revolutionary is cool. So to the extent that you’ve made a billion dollars, you’ve probably become uncool.

I think the perception of wealth and power is that things just become easier and easier when in reality as you raise the stakes things become more stressful.

Facebook is such a basic utility. It's something that is such a part of peoples' lives, I think it's hard to imagine it going away.
