UPDATE: I've long given up on this, so spare me the lectures !
 
 
I'm right handed and have played the guitar right-handed since day 1. But for a while now a big "what if" has been bugging me, triggered by the fact that most left-handed people play guitar right-handed
That, along with some people's comments about how lefties playing right-handedly have an advantage using their dominant hand on the fretboard, got me thinking: What if that is actually true? Considering how clumsy and slow my left hand is on the fretboard, I had to know if my dominant right hand could do a better job.
So I picked up an old classical guitar that was laying around unused and restrung it to be played left-handedly. And I have begun the slow process of teaching my left hand to pick and my right hand to fret.
The toughest part is at the very beginning, where each hand wants to use its muscle memory to execute the scheme dictated by the brain. Of course, since I was holding the guitar backwards, muscle memory was useless and getting in the way so the first thing to do was to overrule it. Granted I can still play right-handed, by every day my hands become freer from the bonds of their past roles and I think I have almost gotten to point blank, where I can start teaching them the new roles.
I'm wondering now, as a new beginner, if I should take the quick "noodle-around" way I took when learning guitar for the first time, or if I should focus on doing it slowly and by the book and taking the time to complete every step of the process instead of rushing to the next one... I know you'll advise the second one, but it has one disadvantage (other than my lack of patience): the comparison between my left and right -handed playing will be compromised as I won't be able to tell if the difference is due to proper training, or natural dominance or both.
 
Another issue that freaks me out a little is, what am I gonna do with my righty guitars if I turn out to play better left-handedly? That is a question I have not answered yet. Granted I will be able to play it, but what is the point of keeping "righty" gear if I'm better at playing leftily? And there's more to it. I like all four of my guitars and 3 of them were opportunities I'm not gonna have again. Plus selling them won't get me my money back, not even close.
A thing I have considered is to keep playing righty and possibly learn how to play a righty guitar lefthandedly without restringing it, for when I want to do something beyond my righthanded playing abilities... Or I could take the time to train my left hand until it becomes as agile as the right, or maybe more... but I don't have the patiente.
Of course you wonder how come I have the patience to learn to play guitar all over again, but I don't have the patiente to fix my already gained skill. Well, I have more patiente for learning something new than for correcting what's already there... Maybe I should spend a little of my time correcting my left hand's fretting skill.
