The task of finally making a decision to hang up my racquet felt a lot more difficult than winning seven matches in a row in the Australian heat. It took me several agonizing months to finally come to the decision that my chronic injuries will never again let me be the tennis player that I can be. Walking away from the sport, effective immediately, is the right decision for me and my family.

By the time I admitted that I needed a hip operation, I had denied it for so long that it was a breakthrough to suddenly say, “I need this.” I knew I would probably never dance again, but I had no choice. By that time, I just wanted to be normal. I wanted to walk down the street without limping. I couldn’t tie my shoes. I couldn’t put slacks on. I was the farthest thing from a person who ever could dance and do all those extremely incredible extensions and contortions that we do.

I read that at a key fork in the road moment for me where I just sold CD Baby and had a ton of money. I was like, “What to do now?” And I read this book from this filthy rich old man being entirely honest, and I thought I should just learn from his experience. ... So if what I’m doing seems weird, it’s because I took his advice to heart and I’ve quit the game.

I don't think I could go for another three years. I'm leaving it at the right time, I love it, I've absolutely had a wonderful competition and I've loved every minute of it.

And so I ran. I ran up and down every court After every loose ball for you. You asked for my hustle I gave you my heart Because it came with so much more.
