I was wondering this too. I'm pretty sure I have both.

For instance, I fundamentally think I'm pretty great when compared to any "average person." And even most "high-functioning" people. However, I realize that talent is essentially meaningless in the grand scheme of things without tons of social proof you're always perceived as a nobody, so I still work my ass off and try not to let my own aptitude go to my head.

Is that high-ego or low-ego?
