If you have any interests, you have something in common with someone. Dislikes, lacks of interest. Humans are as diverse as the internet. Perhaps more so
I think we are all incomplete, being humans. We are animals, yet we seem to be consumed with a never ending hole in our heart. We make fire, we build homes, we strive to cure diseases, we explore, we build, we fight amongst each other, and above all we are never satisfied. That is not unique to any one human.
I wish i could say something more helpful, but i don't have a lot to go on.
