I'll let myself obsess over things.

Dedicating myself to actually following through was my single biggest achievement.

Things that burn very brightly, we wonder how long they can keep burning.

If I walk up to a can of Red Bull, I'm thinking about Formula One; I'm thinking about incredible athletic performances. And it helps me choose that can over something else to either side of it.

When I got out of college, I gave myself till I was 30 to invent a product. If I couldn't do it by then, I would just get a real job. And that fear - the fear of a real job - motivated me to be an entrepreneur.

I obsess over things... especially my book projects. It can be very time consuming.
