It's important to note that generalizations about any group of people, including narcissists, can be problematic. While it's true that some narcissists may display a lack of genuine interest in hobbies or activities that don't directly benefit them or boost their ego, it does not apply to all individuals with narcissistic traits or personality disorders.
Narcissism is a complex and multifaceted personality trait. Some narcissists may indeed focus primarily on activities that enhance their self-image, such as seeking admiration, attention, or power. They might engage in activities that help maintain their grandiose self-concept or serve their own interests, often disregarding the needs or interests of others.
However, there are narcissists who may have hobbies or interests that align with their self-image or self-importance. For example, they might engage in activities that allow them to be the center of attention, show off their skills or achievements, or manipulate others for personal gain.
It's essential to remember that individuals vary greatly, and not all narcissists behave or express their traits in the same way. Additionally, while some people may exhibit narcissistic tendencies, it does not necessarily mean they have Narcissistic Personality Disorder (NPD), which is a more severe and pervasive condition.
When dealing with individuals with narcissistic traits or NPD, it's crucial to approach interactions with caution and seek professional advice if necessary, especially if you find yourself in potentially harmful or manipulative situations.
