I don't worry about anything but winning races.
I have to win races. It's not even an option.
It's funny how the whole team gets quiet when you're about to win a Daytona 500.
Obviously, the opinions that are most accurate are the ones that are closest to you - your crew, your friends, your family. Those people know who you are, and that's accurate.
When you cross the line and you've won the race, to me, it's an amazing feeling.
There's always room for improvement.
