The purpose of each workshop listed below is to reinforce logic, as it applies to self-defense. In other words, how do I know what action to take when I’m attacked? Which tactics are most useful to me at that moment? Which tactics are un-useful? Which ones are useless? For example; kicking is a common tactic used in fights. But is it a useful one? Only sometimes. Try kicking while standing in an icy parking lot and see what happens. Or try to kick while seated in a car, or in a crowded room, or on the slope of a hill. Tactics that can only be used some of the time are deemed ‘un-useful’, while tactics that never work are considered ‘useless’. The most ‘useful’ tactics are those which can be used most of the time.
