Hi Gary and welcome to the community.
You’ve already made progress and you’ve already learned to make adjustments to your own guitar. Impressive stuff.
A couple of places you may wish to check out:
There’s a few old 'uns in these parts: Older guitar students / Can 'old dogs' learn new tricks? - #55 by Jamolay
If you’re likely to want to keep a diary type learning log of progress etc: Learning Logs - JustinGuitar Community
If you wish to take inspiration from other JG students posting recordings of their own learning progress and playing: Progress & Performance: Audio-Video of You Playing - JustinGuitar Community
