After watching a lot of poor golfers on the course, and reading a lot of threads on this forum, I've discovered a lot of things that we novice/intermediate golfers do to "improve" our game, which are actually hurting us. And many of them stem from the innate desire to "man up."
I've started the conversation with this list of common errors related to male chauvinism. I will gladly admit - at one time or another, I have been guilty of most of these crimes myself. But now that I've personally benefited from curbing my libido, none of this bothers me anymore.
-Swinging way, way too hard.
-Spending all your time on the range perfecting your big drive, and none perfecting your chipping and putting.
-Dropping $500 on the latest driver, which will likely perform no better than a basic model.
-Buying any driver with a loft that is way too low (I've seen a lot of novices with 9's in the bag)
-Using a Pro-V1 when what you probably need is a decent 2-piece distance ball.
-Buying stiff shafts when regulars are probably more appropriate for your swing speed.
-Not wanting to convert lower irons to hybrids, because "hybrids are for wussies."
I'm sure there's more. Please, add to this list with your own "Viagara" moments, or ones you've seen others commit.
