Hi;
I am about two months myself. I made it through the 5 chord power pack. I took Lisa's advice and was not overly concerned about mistakes. Now I am up to the Keys. I am on the first key of G. Here is my line in the sand. I will not move on till I can make all of the changes cleanly almost all of the time. Everyone makes a mistake or two. I plan to use this method as I go through the other keys.
