A narcissist is an individual who displays a personality disorder characterized by an excessive sense of self-importance, a constant need for admiration, and a lack of empathy for others.
They often have an inflated view of their own abilities and achievements, seek constant validation and admiration from others, and can be manipulative and exploitative in relationships.
Narcissistic traits can range from mild to severe and may negatively impact their personal and professional relationships. Narcissistic Personality Disorder (NPD) is a clinical diagnosis for individuals exhibiting these pervasive and disruptive traits.
