The business model of racing is not a pretty one.

I'm not a robot; I have a personality and I have emotions. I have a humorous side to me and an angry side to me.

The business model of racing is not a pretty one.

I don't feel like I've really changed. Maybe I have let people see more of me than in the past.

Either you focus, or you hit something really hard.

I thought long and hard about my future this past year and during the offseason, and I've decided 2015 will be the last time I compete for a championship.

Racing is not what I like to do; it's winning.
