I was born left handed.
Write left, throw left, etc.
When I took up the game, my dad said this; "most courses are set up for a right handed swing.
A right handed swing is left arm dominent.
I should learn to swing that way."
I did and never regretted it at all.
My game came around very fast as my left arm is the stronger of the two anyway.
When I started, there were not many left handed clubs.
There are a lot now but, learning right handed, I never had the problem.
