pride - high value, feeling, or opinion of oneself (always positive)
dignity - is usually when someone conducts themselves with worth, and self-respect
self-esteem - a notion or impression that one has about themselves (can be negative, positive or neutral)
***Pride although always positive in terms of self esteem does not always produce positive outcomes. Pride can hinder the reality of a situation, for instance if a person has too much pride (thinks too highly themselves) it might over shadow the negative aspects they need to work on.
