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 think self-awareness is probably the most important thing towards being a champion.

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

Trust and respect is something you earn, not something that is given.

When a child signs up for tennis, he or she is put on a team. I put them in a circle and then I make sure they name their own team. I would have them do their skill drills as a team and their fun drills together as a team, then they have to have a match at the end of every week. They can't just have what they call a lesson today every week.

I've never cared that much for cementing my place in history. Sports is so transitory, so ephemeral. It just seems like so much nonsense comparing me to Helen Wills Moody or Suzanne Lenglen or anybody else from some other time. One lesson you learn from sports is that life goes on without you.
