In America, we love to give people second chances too - as long as you admit you were wrong and come back and do it the right way.

It is very dangerous to have your self-worth riding on your results as an athlete.

Even the poor can be fat in the U.S.

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.

I think the Davis Cup has some untapped potential. It should be as prominent as the Grand Slams when it takes place. If you put it together with Fed Cup for an organized, nationalistic team competition taking place in a central location for two weeks, I think that would be beneficial from a fan interest stand point, from a media stand point and from a television stand point.

I think there's no reason the Davis Cup couldn't be as powerful and popular and profitable as any of the four majors are today, given some changes.

I will do everything in my power to make sure people are aware that our team is out there fighting the good fight for the tennis fans of the United States.
