The United States is the only country where a driver can have a successful career - either in stock cars or IndyCar - and he won't need a passport.

Desire is the key to motivation, but it's determination and commitment to an unrelenting pursuit of your goal - a commitment to excellence - that will enable you to attain the success you seek.

I don't have any feeling of accomplishment about anything unless there's a lot of risk to it.

I don't have many superstitions, just dumb things I don't talk about. I will not sign an autograph with a green pen.

What I learned is that in business you must make decisions based on facts, not react with your heart.

The passport changes but the blood doesn't

Do it no matter what. If you believe in it, it is something very honorable. If somebody around you or your family does not understand it, then that's their problem. But if you do have a passion, an honest passion, just do it.
