We take for granted the way things are in our heads... the way society functions, the way we relate to one another; all the ways we "live." The rules we follow, internal and external... when and what we eat, how often, when we should sleep, how long, how many hours we shall work or not work, what we shall do for work, how we play, etc., etc., etc. Habits. What is valued and what is not. Conformity. Norms, what is normal?
(the madness of the ego is/has been "normal")
