Positive People Have Real Problems.....Isaiah Hankel
I agree that positive is not the same as being a Pollyanna. It is just choosing to pay attention to things that are easier to ignore, and not paying attention to things that are easy to pay attention to. Specifically, we're wired to notice perceived existential threats and to pretty much ignore the opposite as irrelevant to survival. Because natural selection, selects for survival, not for thriving or enjoyment.
So if we want to enjoy life ... we have to train ourselves to do so.
Yes kinda ties into your racial check yourself post. "Being self-aware and accountable".
