You have to look at each tie and look at what your options are.

The dumber you are on court, the better you're going to play.

I am there to play tennis and represent the U.S., but I'm also aware that not everyone's going to be able to think that way.

There are only four U.S. tournaments that the very best players in the world play every year - Palm Springs, Miami, Cincinnati, and the U.S. Open. So how would golf or NFL or NHL fare if there were only four times a year that their very best were visible? Tennis went international, and for us to expect it to be popular media-wise is very naïve. And that translates into children and families being interested.

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.

If you don't want to practice, unless you have a hard-nosed coach, you don't have to.

Without a doubt, there's huge satisfaction when a relatively smaller nation can take on a bigger nation and defeat them. There's a lot of pride in that.
