Anything can happen out there on any court.

It's one-on-one out there, man. There ain't no hiding. I can't pass the ball.

Once the US Open is over in the States, mainstream America doesn't really follow tennis, unless you are a true tennis fan.

Retirement is a work in progress. I try to figure out my day, and what I know about myself is that I need structure.

Throughout my career, my mind rarely wandered, and I was never sidetracked by distractions, no matter what I was going through off the court.

A champion is suppose to hate to lose, and it wasn't like I was ever crazy about the idea. But I learned to deal with losing without having my spirit or confidence broken, which would help immensely over time, not just in the big picture but even in specific matches when I found myself in a jam. Fear of losing is a terrible thing.

I did it my way, and I have no regrets when I look back on my career that it was just a big focus for me.
