There are things we can't control - like the wins and the losses.

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.

I think all of us are shaped by the choices we make.

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.

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.

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.

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.
