[Mr. Jelly]

It sounds to me you want to be motivated to play the same thing over and over like when you were young. That dog won't hunt at 68. I'm about your age and I play about like you do give or take. I had a couple of styles of music and guitar playing that I wanted to do a deep dive into. That lasted several years but now it's over. Along this journey I have also focused on finding the songs and music that I like to do. When I say what I like to do I mean stuff that I find myself wanting to get going and do it. Then work at doing it well, as in learning how to do it in the most sophisticated way you can. Make the music that you enjoy doing. The trick is to get rid of the other stuff that waists your time and effort.
