I've been considered inferior ever since I can remember! Then again, it stopped bothering me a couple of years ago, when I considered who was considering me inferior........ I don't consider myself superior or inferior to anyone.
Definitely view myself as superior to some and others as superior to me, though also view some as equals in some way or another. Superiors, inferiors, and peers are gauged in various ways, some by life experience, some by lifestyle, some by intellect, and some by morality, though usually a combination.
