I think the release from the feeling that nothing you do is good enough (in teaching) has been the best thing for me. To move to a completely different career and be successful in it within the space of 2 years has been a revelation. The virtual pats on the back that come from clients and my boss are so welcome after 5 or 6 years of negativity that frankly just wears you down. It IS a big step to take (especially when you've been in teaching a long time) but I do not know of a single person who regrets making the move. So to those people thinking of making a leap into the unknown then my advice would be DO IT.
