The mistake I really learned from was in 2005, leading the Indianapolis 500. I had a decision whether or not to save enough fuel to finish the race - which meant slowing down - or going all-out for the win. I went conservative and saved enough fuel to go to the end but finished fourth.

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

When pressure's on and when the spotlight's on, I feel like it ultimately ends up becoming some of my better moments.

Sometimes it takes looking at the past to really be able to move forward and learn from it.

I'm a big believer in everybody being themselves. If not doing a swimsuit calendar is yourself, that's great. But if doing a swimsuit calendar is yourself, then you should be able to do it. What I do outside the car adds to who I am and expresses a different side of me.

On Memorial Day, I was out floating on Lake Norman and came across Denny Hamlin. We struck up a conversation, and one of the first things we were talking about was how much it helped him when he started racing the Cup car and how much it helped his Nationwide program.

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.
