This is an amazing program, and totally as advertised. Tomorrow is one week since starting 30 day challenge. Today, I went back to an old unmotivating beginner guitar routine, just to see what it was like, and the quality of my playing was night and day. The only teensy glitch is that I'm tormented by the rhythm of the boogie, it just feels off to me, who knows what that's about, it must be an idiosyncratic reaction. In any case, I'm so very glad to be doing the TAC program--it's truly astoundingly effective. Thank you Tony for figuring this out and making it availalble.
