I'm sure you've heard of the snowflake way of thinking- no snowflake is the same, each one is completely different from the other. Which is exactly like humans, of course I've met people where I've thought oh we think so similarly or oh we must be twins; but honestly knowing there is no one like me, or you, or anyone else for that matter is mind blowing sometimes. We brush it off when caught up in daily life, but the fact that there is no one in the universe like you is 100% fact. I also love the diversity and agree with you, if everyone thought the same way and did the same things there would be no debates or confusion or curiosity. The purpose of life is something I think every individual should have a different concept of. Personally, I still don't know what mine is! It's hard to think about, but then again it's worthwhile to think about too!
