Narcissism is a personality trait characterized by an excessive focus on oneself, often leading to a need for admiration and a lack of empathy for others. People with narcissistic tendencies may believe they are superior to others and expect special treatment. This behavior can stem from various factors, including upbringing and social influences, and can affect relationships and personal well-being. In extreme cases, narcissism can develop into a mental health condition known as Narcissistic Personality Disorder. Individuals with this disorder may struggle to maintain healthy relationships and often react negatively to criticism. Understanding narcissism can help in recognizing its impact on both the individual and those around them.
