I try to shrug it off as a minor annoyance that whenever I do something successful, every capitalist out there wants a piece of the action.

What Facebook stands for in the world is giving people a voice and spreading ideas and rationalism.

Some of the best ideas throughout the company's evolution have been from places all throughout the company whether it's an engineer or someone on the customer support team. Just different areas around the company.

This is a perverse thing, personally, but I would rather be in the cycle where people are underestimating us. It gives us latitude to go out and make big bets that excite and amaze people.

The biggest risk is not taking any risk.

So many businesses get worried about looking like they might make a mistake, they become afraid to take any risk.

Find that thing you are super passionate about.
