If Serena Williams played the men's circuit she'd be like 700 in the world.

There's something deeply satisfying when it succeeds, but I'm not going to do another book just to put my name on something and make some money if it's not something I deeply care about.

We all choke. Winners know how to handle choking better than losers.

Serena Williams best female player ever - no question.

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.

I'd like to think I could have and should have won more, but that's not the point. And I was at the point where I was playing great tennis in the mid 80s - the type of tennis people hadn't seen before - and I was very proud of that.

If, in a few months, I'm only number 8 or number 10 in the world, I'll have to look at what off-the-court work I can do. I will need to do something if I want to be number 1.
