When I meet someone, I consider how normal their life is. I do this not because it’s a one hundred percent accurate heuristic on how much I’ll respect someone, but because it’s damn close. If you have a totally normal life, then there are only two possibilities: you’ve thought through every aspect of your life and miraculously agree with society on each one, or you don’t think at all. I try not to associate with people who don’t think.
Greatness is an absolute impossibility without thought.
