Being nervous isn't always the worst thing for me.

I think you have to feel comfortable with your car. You have to go into Turn 1, every lap, with confidence. You have to be sure of yourself and your equipment.

I've read stories that are set in a celebrity's house, and you know where it is and what it looks like and what's inside it, and that's not something I want anyone to know.

My first Indy 500 was one of my high points. I ended up qualifying fourth and I finished fourth. I had a win in Japan a few years later, and then qualifying for Daytona was great as well.

I didn't want to fall back. But I realized it was more important to make it to the end under my own power than to run flat out in the lead or in second and then run out of fuel with a lap to go.

We don't do things we aren't good at by nature. I wouldn't play basketball because I'm only 5' 1". Find what you enjoy - whether it's racing, flying a helicopter, being a doctor, or stitching clothes together. Once you've done that, you have the passion you need.

Racing is been my profession since I was 19 years old.
