W. Timothy Gallwey

The more you try to control your body, the more it will resist.

Concentration is the ability to focus on what you want to happen.

The mind is a powerful tool, but it can also be a source of distraction.

Your mind is your own worst enemy.

The key to mastery is the ability to focus on the present moment.

The game is won or lost in your own mind.

The art of playing is the art of letting go.

Learning is a process of discovery, not a process of instruction.

The most important thing is to be able to concentrate on what you are doing.

The game is played in the mind as much as on the court.
