Andrew Creighton, who ran Europe for us and who now runs the company day-to-day, would always go to the people he would hire and say, "Look, I don't know what it is, but whatever this guy says comes true because he's got some sort of weird self-fulfilling-prophecy thing." And that's exactly right. The reason I was so bombastic or whatever was because you have to believe it.

I came to America from Canada because Canada is stultifyingly boring and incredibly hypocritical.

Look, I've had four kicks at the can. You've had a tremendous career. We're also happy. We've loved. We've lived. We don't starve. We haven't been shot in the gut. So at that point, I started getting a little more serious about the content we were making and the business and building the business. I also became more serious about life and being happy. I got married, I have kids - I'm happy at a cellular level now.

You have to make those mistakes. You have to do the work. You have to fail. I also realized that I should practice what I preach, which is that if you only do get one kick at the can . . . When you go to places like Africa or Asia or the Indian sub-continent, you realize that a lot of the people there don't ever get a kick at the can. There are no "kicks" at the can - you just don't have that shot.

I'm addicted to when people are bringing you around their country, telling you their stories. They become so enthusiastic, so passionate.
