When you're friends with someone, you can't just go out to dinner and say 'O.K., now this is a date.' You've got to do something very different.

My closest adviser is my wife. It's nice to have one of the smartest people in business as your life partner, and someone you have dinner with and breakfast with.

I go home, I have dinner with my wife and kids, and after my kids go to bed, I'm back online doing stuff.

I am at home with my kids from 6 to 8. If I have a work dinner, I'll schedule to have dinner after 8. But we're working at night. You'll get plenty of emails from me post-8 P.M. when my kids go to bed.

You want to hire great people and give them the opportunity to fail. You need to let them figure things out as they go along. If they fail repeatedly, then you probably have to find a different person, but if you don't let people have that opportunity to fail, they don't get to learn and grow and try things.

I run the largest survey company in the world. It just so happens to be the second-largest company run by someone in my house.
