The highly positive/encouraging approach and the lack of pressure to achieve "perfection" that is the basis of TAC is the key for success for me. It diffuses the frustration and stress I have often felt in the past and allows me to make "mistakes" so I can learn from them. It has been said that there are only three ways we learn, we make a mistake, someone else makes a mistake or we get lucky. In other words, two of the three ways come from "mistakes." After all, if we never make mistakes we are only doing what we already know and are not learning.
