Nobody!

Nobody teaches him or herself how to golf and arrives at an optimal destination still intact and more than glancingly happy … even sane! Golf is not a contact sport but it delivers more than its deserved share of bumps and bruises … ruthlessly and at it whim. “When do I get mine?”
Confidence, Comfort and Consistency’ can be very flirtatious and illusive. You think you’ve ‘Got IT’ and moments later you know you do not … three curving and crooked with one straight will seldom produce a prolonged ‘Golf Smiley Face’!
Golf is just too demanding and hungry for the ‘Physical and Mental Truth Of This Great Game’ to enable or allow the ‘Self Taught’ avenue.
