I mean in the grand scheme of things there are only a handful of types of people, maybe a few hundred and those types repeat over and over. Everyone has their own unique experiences, personal drama and relationships, but their behavior and core traits are shared with probably millions of people throughout history. Thinking you are unique is not a rational belief and if it becomes integral to one’s personality (like it has to millions of people before them) I think they should be mocked, just for the sake of getting their heads straight.
It’s not that you aren’t allowed to be the most important character of your story, it’s just that you shouldn’t think that’s because you are something that never was before and never will be after.
