It does take a great hunger to be successful at anything.

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.

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

What I like about the USTA is that it's developing systems to help the coaches coach better.

Hell be lucky to last five or six years on those knees. What it might have to come down to is playing less on hard surfaces and playing more on forgiving surfaces.

You can look directly at the NFL and see how successful they've become because they have central control, central voice, and it doesn't mean that the owners don't have a say, but the commissioner runs it, and he's the one who speaks for them when they go out and do commercial deals.

There are things we can't control - like the wins and the losses.
