I understand...I've always believed that anyone that REALLY wants to learn to play... "will play until their fingers bleed!" which is saying the same thing a different way. I'm just thinking that with the diversity of learning types, there would be corresponding "systems" of approach for the different personality types. I guess what GT is trying to provide is a number of general tools that any learning type can utilize, in developing their own system of learning guitar, thereby creating their own means of "tracking" their progress.

Sorry, I am just thinking out loud as someone who is trying to create their own system of tracking..... just about there I think....:) :)
