No one cares about the Davis Cup. How many people know I won five Davis Cups and seven majors, but that I rarely played the Australian Open?

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.

On a given day, Serena Williams could beat some players. I believe because she's so incredibly strong mentally that she could overcome some situations where players would choke 'cause she's been in it so many times, so many situations at Wimbledon, The U.S. Open, etc. But if she had to just play the circuit - the men's circuit - that would be an entirely different story.

Everybody loves success, but they hate successful people.

Tennis is a funny game; unbelievable highs and the lows are just as low.

My greatest strength is that I have no weaknesses.

I have never seen someone point after point that just gives it everything.
