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.

You have got to be willing to be poor as an entrepreneur.

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

At every point I am besieged by people who would like me to conform to some social norm of whatever sort of social group they expect me to be a part of. I never have any identification with these social groups.

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.

What comes after the revolution is inevitably bureaucracy. Whoever wins the revolution builds a bureaucracy

It would be incredibly presumptuous and self-serving of me to believe that Facebook was the end of history. The only way it could possibly be the end of history is if it becomes some sort of artificial super intelligence that takes over the world.
