This question already has an answer here:
Is there a relative diagnosis for someone who can't simply adapt to and/or use something that is already established? This type of personality would also need to have their own idea to validate their selection/alternative for peer acceptance. It could be either severe (I'm guessing this would be narcissistic personality disorder) or mild.
Is this common or categorized in some way? And are there ways of dealing with this type of personality/behavior?
