Over the last twelve years, Stephan Ehritt-Vanc and Andreea Ehritt-Vanc, founders of the Pro-M International Tennis Academy, have played in or coached several players in more than sixty Grand Slams. In their guidebook, Pro Rules, they offer proven principles and a set of values that can help tennis players of all ages improve their game, achieve goals, and ultimately maximize their potential. Presented through five main elements--experience, acceptance-action response, respect, real self-confidence, and mastering the zone--Pro Rules guides tennis players to not only control their physical play, but also their mental play as well. You can learn how to - act like a pro in any situation; - deal with bad calls; - focus despite distractions; - analyze, predict, and respect an opponent; - strike the balance between self-confidence and overconfidence; and - live in the present tense. Pro Rules relies on the lessons of two experienced tennis professionals to share an innovative way of looking at life--both on and off the court--that can guide tennis players to find their professional core, learn control, and master their game by following their instincts with mastery and precision.
