The fallacy in that logic is that just because it worked for you or some famous celebrity, it will work for ALL lefthanders.I can relate. I am a total lefty. Baseball, tennis, basketball. Except guitar. In 1963, not many lefty guitars around.
My future brother-in-law was a bonafide righty, and was kind enough to teach me on his guitar. Fretting was
tedious at first, but I finally got it. The only thing, AND I DO MEAN, ONLY THING, I do right handed is play
the guitar. It's strange what you can do, once you get use to, now is it?
