I spent a month reviewing all the available online guitar lessons I could find. I found Tony's Accoustic Challenge early on but kept looking to see what else was available. I chose TAC and am I ever glad. I took weekly guitar lessens 20 years ago and more often than not, I would not practice between lessens and the consequence was I never got anywhere with guitar. I really like all the thought that has gone into this program, the micro-habits idea, the personal commitment, it has been a game changer. I have been giving it a minimum of 10 minutes (usually more like 20 - 30 minutes) 5 or 6 days out of seven. I can't believe how quickly I have progressed. I'm much farther in 5 or 6 weeks than I ever was with several years of lessons. And I'm enjoying it. Lastly, I just love Tony Polecastro's overall vibe, it's the thing that pulls it all together. Very update and relaxed, and geared towards people like me who are re-beginners. It's like he reaaly remembers exactly what is was like to be in our shoes. Just a great course so far, I highly recommend it!
