Be happy. If you're successful but unhappy, that's emptiness.

My greatest strength is that I have no weaknesses.

Equipment's the biggest change. And the guys have been getting bigger, stronger, more athletic - so the game has become more of a track meet instead of a tennis match, in a sense.

If Roger stopped right now and never won another match, to me he'd already be one of the greatest players to ever play the game. To me, he's the greatest all around talent that I've ever seen.

If you want to be a tennis player, then mould yourself on Roger Federer. I won three Wimbledon titles and I wish I could play like him.

I know being a linesman is a thankless job, especially with guys like me around.

Borg's won Wimbledon four straight times and out there he has just lost an 18-16 tie breaker. You'd think maybe once he'd let up and say forget it. But oh, no way.
