It was okay for Wayne Gretzky's dad, for instance, to give him a hockey stick, or Joe Montana's dad to give him a football, or Larry Bird's dad to give him a basketball, but it wasn't okay for Gloria Connors to give her son a tennis racquet.

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.

With everything else that would swirl around me when I got involved in it, tennis was my main concern.

I've been kicked in the teeth more times in tennis than the law ought to allow.
