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.

Back in East St. Louis, tennis wasn't the real thing. If you weren't playing baseball, basketball, football, you were kind of on the outside.

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.

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

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

Greatest thing in life: Winning a tennis match. Second greatest thing in life: Losing a tennis match
