No, like I said, my dad was never really part of the tennis. His involvement around what I did with the tennis and with my mom and my grandparents was really not a part of my life.

[In the modern game] you're either a clay court specialist, a grass court specialist or a hard court specialist... or you're Roger Federer...

I think my greatest victory was every time I walked out there, I gave it everything I had. I left everything out there. That's what I'm most proud of. I can't go win Wimbledon anymore, so if what I've done in the past is not good enough, let it go. Because I'm certainly not sitting around thinking about it.

From where we lived, to practise in St Louis was an hour-and-a-half drive each way, so that took a lot of the time. So really, our lives just took different paths.

Rather than viewing a brief relapse back to inactivity as a failure, treat it as a challenge and try to get back on track as soon as possible.

Tennis was never work for me, tennis was fun. And the tougher the battle and the longer the match, the more fun I had.

When you're hot, anything can happen.
