I signed up for TAC because the online ads I saw described my situation to a T (recently retired, had a guitar for 20  years, made noise with it off and on, but never got past a few basic riffs etc.). With TAC, I find there is a structure to the course and I'm looking forward to learning each day's lesson. Prior to TAC, I would get bored/frustrated after 10-20 minutes and put the guitar down. With TAC, I find that I am working on the lessons daily for 1-2 hours and never getting tired of it. Best of all, my wife has commented (without prodding) that she hears a confidence in my playing that she never heard before. Still a long way to go, but I am enjoying every minute of it!There are still plenty of days where I feel like I'm drinking from a firehose, but I'm game to keep going.
