Got my 66 Hagstrom III back, reconditioned now, and have embarked on playing again for the first time in 50 years. Feels good, not all is lost, and I'm enjoying the program. I like the emphasis on keeping it moving, over achieving playing perfection (like that's a worry!). I agree that just playing guitar regularly will build the competence better and quicker than obsessing about a particular lesson. I'm also thinking about trying to figure out songs I've always liked down the road a bit, so I like your incremental building of our foundational skills in the context of playing a particular tune over a week of exercises. It's been an enjoyable challenge, proceeding at my own pace, with lots of little wins along the way.
