I'd have to say yes. I never was very good, so that's not much of a claim. Never in a band. I've been working on actually using my pinky for lead stuff. I joined a local monthly jam to force me to learn new songs and get out of the living room. I'm giving my brother lessons, and he's an engineer and interested in the theory that I never learned. So now he's reading theory and I have to at least try to keep one step ahead to answer his pesky questions. (Versus my prior "I don't know why... just shut up and play it like this!" teaching method.) Slowly learning some Frank Sinatra-esque jazz stuff. Takes a while to get those jazz chords into muscle memory, after decades of nothing but Beatles, Stones, Led Zep, etc. Makes playing challenging and it's fun to expand the living room set list.
