Belief - that which you hold to be true, despite evidence to the contrary. My deepest held belief:
All people are always awesome. In all ways, and always.
It is a selfish, and self-full belief. It removes the need to judge another, moment to moment. It spares up mental cycles for a more important question: Does this situation work for me?
The person I am interacting with, is awesome. And is being awesome. Yes.
Their behaviour may be "a tragic expression of an unmet need" as Marshall Rosenberg said. And they are awesome for doing their utmost to get that need met. In all ways.
The judgement becomes this: Does this work for me, right now?
