Originality. An idea that is near impossible to realize. Everything we could possibly think or say or do has been thought, said and done before, right? Recycled beings, endlessly rediscovering feelings that have already been felt. Tough then, to find meaning in it all. Why bother? We aren't covering any new ground anyway.
But therein lies the magic. Humans are social animals. We strive to belong. We find solace in commonalities. That's one of the reasons why we appreciate things if they are "relatable". To put it in a nutshell, it's pretty damn cool that you and I can feel the same things. That our thoughts can align with each other. Because, if that wasn't the case? I think it'd be a pretty lonely existence.
