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.

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.

There's plenty of anecdotal evidence that most champions are born into certain environments and encouraged early. Then, later on, they might get some assistance from their federations.

People handle stress in different ways.

The airplane has had a big impact on my life.

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

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