On the best days, I stop pleading, stop bargaining and watch-checking and fall into a rhythm so satisfying that I simply forget I’m working. So much of my writing day feels like well-digging. Sometimes I dig 200ft down before coming back up, dry. Every day I search for water.

A good coach is somebody who has a clear concept of what they want and what they love in the game, is capable of expressing it in an understandable way, and is able to obtain it on the football pitch. They're also someone who loves to help others. This means something more than just going out and coaching a session, they really try to understand who a player is and find the key to helping them. All players have different problems, and we have the capacity to help them solve them.

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.
