‘The mental side of tennis is extremely important. How you feel, how you hit the ball, how you read your opponent’s game, et cetera. Mindset teaches you, and shows you, how to control those aspects of your game. You find out how to control your own mind and to determine how you react and function. This book’s clear translation of theory into practice has helped me to achieve a great
sense of inner calm.’

that is even more important... your life! Congratulations to the authors. Enjoy and apply it!’
