I teach several classes per week, train in other teacher's classes, organize seminars, set up holiday training events (annual Memorial Day and Labor Day trainings and picnics), help scrub the mats after the Thursday night class, and typically lead post training beer waza
(I also keep the fridge stocked with frosty adult beverages).
However, I voted critically active for one very important reason: I scrub the toilet!
(Ours is smaller dojo run by a Board of Directors, who all work very hard to keep the place open and running smoothly. Kudos to all the members of our Board)
