Golf has 3 competitors - other players, the course, and yourself. Leaderboards measure how you performed against others; score against Par measures how you performed against the course. The GYRA Mental Scorecard allows you to measure your performance against your primary competitor - yourself - per shot, per hole. This is a game-changer. "You may never play golf the same way if you start measuring your mental performance on the golf course." Gary Player, World Golf Hall of Fame "With the introduction of the GYRA Mental Scorecard, you are now able to track your emotions, thoughts, and behaviors to be able to better yourself for future situations." Jason Gore, Player Relations, USGA "GYRA tools have given me the skills to manage my emotions and thoughts throughout the up's and down's of tournament golf." Seamus Power, Olympian, PGA Tour Player "I have been coaching college golf for 20 years. The difference between a good vs great player is usually their mental approach to the game. The idea of having a scorecard for golfers to describe and track what is happening in their mind is groundbreaking." Tim Straub, Davidson College "This book should be required curriculum for golf academies, teaching professionals, caddies, and players." David Ross PGA Lifetime Member, Ross Academy
