Us going out there and performing our best. That's how I define success. I'm not going to define it for us by the wins and the losses as much as by the effort and how we handle ourselves.

We lose a lot of young athletes because tennis is such a difficult sport. It's not like kicking a soccer ball.

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.

There's no evidence that says that the money a federation has translates into success. I hope that that will change.

When I turned professional, what I was really aiming for was to be in the top 100, try to hold the top 100 for ten years, and just be in the show, and have a nice career. It's more than I could have ever hoped for. I worked awfully hard for it, but there are other people who worked just as hard and didn't get the breaks. I recognized that I've been lucky and being able to live this life that I wanted since a young age. I really went after it with everything that I have and somehow it worked out.

When your four biggest tournaments all operate relatively independently, and the ATP and WTA tour operate independently, and you have Davis Cup and Fed Cup that operate independently, it makes it a tough message.

It's hard for anyone in the 24-hour news cycles that we all live in now to follow something that the first round is played in March and the final finishes in December. I understand the challenges there.
