I'm a returning player, who, exactly as you described, would pick it up, play for a while (sporadically), become dissatisfied with my lack of progress and put it back down...40 years ago. As I neared retirement I decided I wanted to play again. And once more found myself falling into the same pattern, playing the familiar licks but never really progressing. Then I came across your program. The 30 day program at first was a rehash of what I already knew but I stuck with it, and began to notice my playing skills slowly improving each week. It's just like you said, show up and put in your ten minutes, which in my case often turns into two or three hours, and the consistent application will yield results. Many of the lessons have me using skills I already have (but didn't understand the application) as well as the focus on something new each week keeps me "showing up". The structure provided is translating to my electric guitar as well.
