Even the poor can be fat in the U.S.

You need to make sure everyone is healthy first and foremost.

The good news is I have time.

You have to be extreme to be exceptional. I couldn't revel in being number one. I had to get to zero. When my fitness was at its peak, I was intimidating. I made guys cave in. They'd be dejected in the locker room after matches, and I'd go out for a run, as if it wasn't enough. I'd rub it in their faces. I meant to do that.

Tennis doesn't encourage any kind of intellectual development.

I think there's no reason the Davis Cup couldn't be as powerful and popular and profitable as any of the four majors are today, given some changes.

What I've seen historically is winning is a major aloe. It solves a lot of problems.
