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.

There are a lot of people building small ideas now. There's an idealization of being an entrepreneur, but the most important thing is to have a really great idea.

I used to do volunteer work in poor areas of Cairo, and people would gather their money together to get a satellite dish.

I did love 'Dirty Sexy Money' quite a lot. I loved my tenure at 'Scrubs' quite a lot. 'ER' might have been my favorite guest star thing. 'We Were Soldiers' meant a lot to me.
