What separates the winners from the losers is that they can deal with doing their best while still coming up short.

You can drill down on where hunger comes from and figure it out from there, but there absolutely has to be a sense of urgency if you're going to play tennis because you're the team - there's no one for you to rely on but yourself.

Getting to number one in the world without a coach is highly unlikely.

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.

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.

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.

It's really easy to find your friends when you're playing away. You have a close-knit group with you and everyone else is cheering hard for their side. There's more satisfaction coming away with a road victory.
