Michael,
You're in good company in here. Lots and lots of us Boomers dusting off guitars and making another run at becoming musicians. I was just rummaging around my cluttered basement and came across an acoustic guitar I've had now for 51 years... and it's in mint condition, if that tells you anything about how little I've played it. Nevertheless, with Strat in hand, I declare; "Once more unto the breach, dear friends, once more!".
In any case, don't be shy about using this forum if you acquire doubts, get confused, or lose motivation.
Sascha
