It's true that some level of narcissism can be found in almost everyone. Narcissism exists on a spectrum, ranging from healthy self-esteem and confidence to unhealthy levels of self-centeredness and entitlement. Healthy levels of narcissism can be beneficial, as they contribute to a positive self-image and the ability to take care of oneself. However, when it becomes excessive and interferes with relationships and empathy towards others, it can become a personality disorder known as Narcissistic Personality Disorder (NPD).
It's important to note that not everyone meets the criteria for NPD, and many people can maintain a healthy balance between caring for themselves and considering others. People who exhibit some narcissistic traits can still have meaningful and fulfilling relationships if they are willing to be self-aware and work on improving their interactions with others.
However, the extent of narcissism can vary greatly among individuals, and some people may have very minimal narcissistic tendencies. Cultural and societal factors also play a role in shaping individuals' levels of narcissism. Ultimately, the degree of narcissism varies from person to person, and not everyone falls on the extreme end of the narcissism spectrum.
