Insanity

Everyone knows the definition of insanity.  In golf, why do some golfers refuse to get REAL help with their game?  I see a lot of golfers who try and figure it out on their own only to figure out that they can't.  Golf is such a hard game to advance at if you don't have proper instruction.  Since golfers can only go off what they feel they are doing or what their 20 handicap buddy tells them they are doing, it is hard to find/fix the problem.  Most golfers swings' don't change very much when they practice or try to improve on the range by themselves simply because they don't know how to fix their own faults.  If you knew absolutely nothing about cars, imagine trying to fix your own!  The price you pay for lessons might be worth it.  Those headaches you get every time you play could be eliminated.
