One of the dumbest things a smart person can do is to start thinking they’re smarter than everyone else.

Anyone who always thinks they're the smartest person in the room is wrong. At least some of the time. I find the most dangerous people are always those who think they're smarter than everyone else, mainly because of the lengths they go to prove it. The smartest people I've met don't really seem to think about it at all.
