Hey John, good on ya!
You’ve started a decade later than me, and I too have many similar feelings/situations.
As you know from the miles under your keel, progress is in fits and starts, but always upward.
This community is a wonderful resource if you find you’re struggling/wondering/noodling with something you can search the community for previous threads that might have addressed your ideas. Or, start a new thread if the search comes up with nothing.
There’s even a group for “Old Dogs” you might want to join, jump in here and see if the smell of the kennel is appealing: Older guitar students - can 'old dogs' learn new tricks?
see you in your posts
Bruce
