Whilst it's been a while since I wasn't naturally compelled to have hands on the instrument daily; and for hours on end...

When those times have occurred...

I just make it a point to do SOMETHING/ANYTHING on guitar; for any amount of time

(not even 5 minutes; just ANY amount of time)

maybe run through a scale; but typically it was

just picking something from my repertoire list (things I can play with ease)

I started that list with simple riffs and melodies

and then it expanded into songs
