Andre Agassi

I've been motivated by overcoming challenge and overcoming the hurdles and obstacles that face me. There still is plenty out there to get motivated by.

Well, I actually tell my son that I don't have any hair because he asked me the same question that I gave it to him when he was born, so he actually still believes that. He's five years old.

Some moments it feels longer, other moments it feels like it's flown by; you can't believe you've done it all that time... Overall, you have a strong sense for the full spectrum that you've sort of traveled.

Sometimes it's just harder to remind yourself about what you're doing and why you're doing it... Other times, you have a great desire for it, but physically you're not responding the way you want. That presents other challenges. Then sometimes it all comes together.

I had moments of my actions and words not reflecting who it is I am - if that defines a punk, then yes, absolutely.

Nothing can substitute for just plain hard work. I had to put in the time to get back. And it was a grind. It meant training and sweating every day. But I was completely committed to working out to prove to myself that I still could do it.
