You might hear that the number one enemy of golfers is fear. Sorry, that ain’t it.
No one is throwing a baseball past you at 95 mph and if it misses the strike zone it could hit you. No one is trying to tackle you with as hard a hit as he can muster.
In golf you just stand there and swing a club at a ball. And if it goes in the water instead of on the green, how are you harmed? What have you lost except a golf ball and a stroke on your scorecard?
The number one enemy is uncertainty — that you have picked the right shot (knowledge) or that you can hit the shot you picked (confidence).
If you have acquired both of those qualities, golf is a simple game.
