If you look at top players - Steffi Graf, Andre Agassi - so many had a parent who was domineering to the point where you really had to question his sanity. It was nuts.

New York can get on top of you if you don't have much money, but if you have money, it's kind of a playground.

There was a point where I really felt I had 'penniless divorcee lone parent' tattooed on my head.

A tennis racket lurks in my earliest memories like a sick relative who had come to live with us. When I look at my baby pictures, there it is, resting in my crib in the place of a rattle or chew toy.

I'm really troubled by the prevalence of single-sport specializations. I want my kids to do as many things for as long as they can. Specialization is a natural thing that should come later - it shouldn't come for 8-year-olds.

With tennis, if you're very good at a young age, you don't even go to your prom. You're down at some tennis academy in Florida where you're on the court 8 hours a day. It's brutal.
