Habits form because we’ve been doing the same things for years, acting out patterns of behaviour our entire lives. Do things often enough and they begin to occur automatically, unconsciously, creating familiar situations with familiar outcomes. Which is why it’s necessary to look closely in order to see them clearly.
A pattern begins life as a strategy. The strategy starts with a desire. Over time, patterns establish themselves as a part of our personality, creating the impression that we have always been like that, when the truth is more likely that we have adopted and reinforced particular ways of behaving over the course of our lifetime.
Our behaviour has been instilled in us by our culture, imposed on us by society, passed down by our family and established by us according to the Script (TA) we have written for ourselves. Growth depends on us examining our conditioning, and then actively choosing to retain it, modify it, or drop it altogether.
