Work as hard on yourself as you do on your golf. What do I mean by this?
To be the very best golfer you can be you have to learn to stay in control of yourself on the course. You have to manage your mind and your body. Working on your body, your swing, is only half the battle one. It is only one half of the performance equation.
Work hard on your game and work hard on the soft skills that complement your game. Work hard on your focus, your confidence and your emotional management. Combined they bullet proof your performance skills when you compete under pressure.
