There was never anything I wanted to do more than play tennis. Never once walked out there and thought, 'I wish I was doing something else.' Not once.

I had true rivalries. Not only did I want to beat my opponent, but I didn't want to let him up, either. I had a rivalry with Mac, Lendl, Borg. Everybody knew there was tension between us, on court and off. That's what's really ingrained in my mind: 'This is real. This isn't a soft rivalry.' There were no hugs and kisses.

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

Big money encourages tanking. In my opinion, tanking is going on even with a lot of the top guys today - it's quite evident.

I never lost a tennis match, I just ran out of time

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.

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