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.

Sports for me is when a guy walks off the court, and you really can't tell whether he won or lost, when he carries himself with pride either way.

I'm a big proponent of Hawk-Eye. I think it's a wonderful addition, not only for the players, but more importantly for the fans.

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

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.

The airplane has had a big impact on my life.

If I had to choose one man to play for my life, it would be Nadal.

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.

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.

The good news is I have time.

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

Long after people forget what you said or did, they’ll remember how you made them feel.

The thing that impresses me most about North America is the way parents obey their children.

They have done this through sexual repression, economic repression, political repression, social repression, ideological repression and spiritual repression.

Look at the history of peace accords in Africa. They have a terrible record. They are shredded even before the ink on them is dry.

Sometimes you have to get rid of something that's good, and tinker with something that's better.

The perfect human being is uninteresting.

Why in God's name do you expect to be accepted everywhere? How is it the world couldn't get on with the holiest man that ever lived, and it can get on with you and me?

Pride is a vice, which pride itself inclines every man to find in others, and to overlook in himself

When strong, avoid them. If of high morale, depress them. Seem humble to fill them with conceit. If at ease, exhaust them. If united, separate them. Attack their weaknesses. Emerge to their surprise.

Do all that you can do in a perfect manner every day, but do it without haste, worry or fear. Go as fast as you can , but never hurry.
