Hi Regan: Good points. I noticed you said "try to correct weaknesses". I agree. The hard part is knowing how to assess where a weakness exists and then (perhaps even more difficult), being willing to adapt, modify, or make adjustments in that weaker trait. I think better instructors are willing to adjust their behavior when they learn of defiencies in an effort to help their students. Unfortunately, for whatever reasons, some individuals are relunctant or just refuse to make personal changes, even when they are made aware or or become apparent. Regards, Barry
