Recently retired, and I highly recommend it. Picked up a used acoustic guitar about 8 months ago. It was right handed and so am I, but do to an old circular saw accident, I’m forced to play lefty. I recut the nut and restrung it and started down this addictive journey. I’ve since bought an Epiphone SG and a Martin X series Special, both left handed. I’m hooked. 
I tried a couple personal instructors, but they lacked a structured plan. I like the way these lessons build one on top of the last.
