People say I'm around because I have a lot of heart, but I know all the heart in the world couldn't have helped me if I wasn't physically fit.

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.

That's something a lot of athletes miss - a lot of them walk away too soon. They don't get everything out of their system. They have a lot of what-ifs when they're sitting around later in life. I don't have that. I got all that out of my system. I pushed it to the brink, I loved it, and when I walked away, I'd had enough.

People don't seem to understand that it's a damn war out there.

I was never part of the crowd.

I don't go out there to love my enemy. I go out there to squash him.
