Hey. I’m early on yet am playing with joy and creativity. My schedule does not allow the standard pace but I come back and knock out several days at a time. A great feature is I can go back and review/refresh previous lessons and see how easy they’ve become as I move along. Bar chords are still tough but I can hit them quick now and again. So, if the question ever arises if you can teach an old dog new tricks, the answer is yes.
