Feeling of Superiority and what to do about it?

Sometimes I can see myself feeling superior to others because of what I know and they don't . I know that it is my ego which raises it head and is active at the moment. I also see persons, who are successful in profession, business, sports display show of superiority just to break the opponent's composure. Often ego needs bolstering and acknowledgement to survive the life's challenges. My question is how to achieve the balance without pampering the ego and without showing disrespect to others, by own accomplishment, knowledge, possession, gender, class etc and carry on.
