That is so interesting, Bags. But, while I agree with you that failure is a useful adjunct to keeping you aware and reminding you that you can cope, success builds self esteem, and that's important too. Maybe you need the balance of both? I am trying not to use anecdotes from personal experience here, but suppose I am referring to them implicitly.
