The emotional push of certainty. Addictive. Holds you there. Keeps you there. Feeds you with that feeling of mastery.
In proper dosages, it’s not a bad thing. I’m writing, choosing particular words when others might do. I’m satisfied after the fact (when I get the visual feedback of the words which re-input, match up with some emotional sense of intention leading to confidence) and continue writing.
I take a step forward and unless I’m in one of my “damn you Pauli and your principle” or start thinking about the boundaries of objects, I’m certain my foot will hit the ground as it had before and support my mass and I allow my body to sway into position for the next step (unless I’m self-conscious and try to take unnecessary control of the process).
Hm, so perhaps that part of it? Certainty keeps you from having to think about things that _generally_ work as predicted. So it has its place. But when it’s overused or misapplied, it can be dangerous.
