I'm enjoying my retirement, enjoying my life. I have two kids and a lot of my time is spent chasing these two animals.

You kind of live and die by the serve.

I made it look so easy on court all those years. No one realized how hard I had to work. No one realized how much I had to put into it. They underestimated my intensity.

When I committed to playing a little tennis in some exhibitions, it was the best thing for me. It got me in shape. It got me out of the house. It got me doing something I love to do.

Choking is being in a position to win, and then experiencing some critical failure of nerve or spirit. That never happened to me. And I can't help but think it was because I was never afraid to lose.

When you come back strong, you are going to have little nagging things that you can usually play through, but every now and again, it is to the point where you can't play.

Anything can happen out there on any court.
