"If a meteor were to hit the Earth, without even realizing it, I'd go to heaven. Well....That could happen...."
Quote from supercell's song Perfect Day.
Humans in general are way too optimistic. You can't expect the best out of anything, so be prepared for the worst. Your morals and values can be torn apart as you know them.
I don't believe in heaven though, don't get me wrong. I'm an atheist.
