I really enjoyed your post tonight as I have fun analyzing people while watching them. I normally try and work out where they are from and what career they are in. Most likely I am wrong most of the time, but it is still fun to try and figure out. I agree I don't need much either and it ain't joining the bears in the woods .
Nothing wrong with being wrong and knowing it. I think some people do it but rarely get the confirmation of their incorrectness and therefore walk away thinking they are right. Ends up in overconfidence and insensitivity to the environment.
