Once a few Facebook employees put together a promising idea and start a company, that's very exciting to people. I happen to think being a Facebook employee is really correlated with good ideas.

Facebook was a very big mission; it really knocked it out of the universe. It's pretty hard to focus on a small idea after that. You really have to be working on something that you believe will be of similar impact.

That's where the good ideas come from: the people, not the boardroom. But you have to be willing to put in the legwork.

There's an idealization of being an entrepreneur, but the most important thing is to have a really great idea.

I'm not really sure where it comes from, but every time I meet someone who says 'I really want to be an entrepreneur' but has no idea what they want to do, I really just think: 'This person is totally aimless.'

I have some ideas on how to fix that. They're not very good ideas, but at least they're ideas!
