Luchnia,
You hit the nail on the head for me. I teach because I couldnt find anyone willing to train me (20 years ago). I taught myself at great expense and time. After two years I finally ran into a guy that buddy boxed me and in two flights he corrected a lot of the bad habits I taught myself. I teach or help anyone because I almost gave up. I wouldnt want to see that happen to others.
