Narcissists often harbor intense feelings of envy toward others. They believe that others are equally envious of them, reinforcing their grandiose self-image. This can lead to a competitive nature, where they constantly compare themselves to others and may engage in one-upmanship.

Narcissism, in psychological terms, refers to a personality trait characterized by a grandiose sense of self-importance, a constant need for admiration, and a lack of empathy for others.
