I started guitar at 59 and am now 61. I picked up a cheap Yamaha that my son left lying around the house. I already played harmonica and sang a bit so I thought I would do some Dylan stuff and I just fell in love with it. Being realistic I ain't never going to be a maestro but I derive so much pleasure and satisfaction through the whole process I am determined to go as far as I can. After two years of regular practice I can see that I have come a long way but sometimes day to day it is not always immediately obvious. At my age you have to be patient even if time is running out. Enjoy the experience. I now have three other guitars alongside the Yamaha which I use as a travel guitar. I have an acoustic and electric amp, a condenser mic for my laptop and a dynamic for my bedroom concerts. ha ha. So to you young man of 37 I say that if you enjoy the whole experience then stick at it and good luck to you.
