In response to "ego"

I was thinking that a hero's feeling would be confidence, not ego, and then I wasn't sure and wanted to look up ego. This definition popped up:
"the one of the three divisions of the psyche in psychoanalytic theory that serves as the organized conscious mediator between the person and reality especially by functioning both in the perception of and adaptation to reality"
So Kai, do you mean the idea of overconfidence, the show-off, the person who will not listen, this is the form of ego you mean, correct? Carissa, what did you mean by it being a motivator? That you would think a certain way of yourself and your abilities and that moves you to live up to that standard or to try to go further?
