Tennis doesn't encourage any kind of intellectual development.

I really try not to read the tennis articles, because a lot of times they're guessing at how a player is feeling, and I like to keep myself kind of open minded about how I'm feeling, rather than have someone else explain to me what's going on.

If they had rankings in baseball, maybe I would have been able to do the math and figure out my chances of being a professional baseball player versus a tennis player. But that was the decision-maker for me, I just thought I was better in tennis.

It's unfair to expect the USTA, just because they make this pot of money, to just snap their fingers and make champions. It's not simple, and anyone who thinks it is hasn't really looked underneath the hood to see how the engine works.

Fear is an interesting energy that we all have to face. Some people step up and aren't afraid but still come up short. And some would rather cop out: "My shoulder hurts" or "I didn't give it my all." They can sleep at night.
