Every time I get into a Nationwide car after being in a Cup car, I feel so much more comfortable than I did previously.

The commitments, schedule and sponsor appearances don't change. It gets more busy, because you get more popular, and the more popular you are, it actually gets more busy. They're like, 'Yeah, let's use her, she's hot right now. Let's do a shoot!'

I'm not tall enough to be a model, but I wish I was 6-foot, because I love it. It's kind of artsy, and I'm artsy. And I love clothes.

To be honest, when I'm home, every day is a Friday for me. It doesn't really matter what day it is for me. A lot of my friends actually have time off during the week, and so it doesn't prohibit me from enjoying myself when I am home on a Monday or a Tuesday.

No matter how good you are, how brave you are or anything, it comes down to that car so many times. Not every time, but so many times.

You have responsibilities and if you want to be the best in your industry you need to have a relentless dedication to your job. I was fortunate to have support from my parents and sister growing up and that helped me a lot.

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.
