Don't go into debt and don't spend a lot. It's not how much money you make, it's how much you spend.

As far as U.S. tennis, we need new stars coming up in the pipeline, but I don't know if we have it.

Bobby Riggs was one of my heroes. I admired him. That's one of the reasons I beat him - because I respected him.

It's just really important that we start celebrating our differences. Let's start tolerating first, but then we need to celebrate our differences.

When I was playing, we didn't have to compete against everybody in the world. Now it's a truly global sport, so the competition's much greater, just like it is for our children in every other area, whether it be in science or technology or whatever you talk about.

I always wanted to help make tennis a team sport.

I didn't really care if I had a coach that much, me personally, because I was brought up to think for myself.
