Hi Andrew: Achieving a deep and accurate understanding of ourselves allows us to be ourselves, act with confidence, demonstrate our competence, and approach each student with a degree of tolerance, acceptance, and patience - because we're not into some "control or authority" trip, that's really offensive and discourages an openness to students. Effective instructors must excerise control and authority; I'm talking about autocratically lording it over students, due to our inadequacy. Regards, Barry
