A narcissist is an individual who exhibits traits associated with Narcissism, characterized by an excessive sense of self-importance, a strong need for admiration, and a lack of empathy for others. This personality trait can manifest in various ways, including a preoccupation with fantasies of success, power, or beauty, as well as an exaggerated sense of entitlement. Narcissists often struggle in their relationships due to their self-centered behavior and difficulty recognizing or valuing the feelings and needs of others. In more severe cases, narcissism can be classified as Narcissistic Personality Disorder (NPD), which is a mental health condition requiring professional intervention.
