“You will find that the more you get into the habit of making the vagaries of your surroundings an excuse for a bad stroke, the more real and powerful will their distracting influence become. If you can bring yourself to treat those trifling distractions, even when they have put you off your stroke, with the silent contempt they merit, you will soon grow to disregard them – whereby you will become a better golfer, and pleasanter.”
