I quit when I get sick of what ever hierarchy I've been implanted in refuses to flatten after consistent attempts (overt or subvert) by myself to instigate positive change. My life is governed by a set of rules inspired from daoism and taijiquan. First and foremost is "Make good change"(The secret trick is to smile, from you heart). If the authoritarianism is standing in the way of this, it's time to move on.
