I can’t promise you that you won’t be tired, he says. But please know this. There’s a lot of good waiting for you on the other side of tired. Get you… - Andre Agassi

I've internalized my father- his impatience, his perfectionism, his rage. I no longer need my father to torture me. From this day on, I can do it all by myself.

Freed from thoughts of winning, I instantly play better. I stop thinking, stop feeling. My shots become a half-second quicker, my decisions become the product of instinct rather than logic.

Tennis is the sport in which you talk to yourself. No athletes talk to themselves like tennis players. Pitchers, golfers, goalkeepers, they mutter to themselves, of course, but tennis players talk to themselves — and answer. In the heat of a match, tennis players look like lunatics in a public square, ranting and swearing and conducting Lincoln-Douglas debates with their alter egos. Why? Because tennis is so damned lonely. Only boxers can understand the loneliness of tennis players — and yet boxers have their corner men and managers. Even a boxer’s opponent provides a kind of companionship, someone he can grapple with and grunt at. In tennis you stand face-to-face with the enemy, trade blows with him, but never touch him or talk to him, or anyone else. The rules forbid a tennis player from even talking to his coach while on the court. People sometimes mention the track-and-field runner as a comparably lonely figure, but I have to laugh. At least the runner can feel and smell his opponents. They’re inches away. In tennis you’re on an island. Of all the games men and women play, tennis is the closest to solitary confinement, which inevitably leads to self-talk, and for me the self-talk starts here in the afternoon shower. This is when I begin to say things to myself, crazy things, over and over, until I believe them. For instance, that a quasi-cripple can compete at the U.S. Open. That a thirty-six-year-old man can beat an opponent just entering his prime. I’ve won 869 matches in my career, fifth on the all-time list, and many were won during the afternoon shower.
