I'd like to branch off from this comment a bit. What happens when your intelligence, like wealth (a comparison I recently started making), creates a gap between yourself and others? What happens when you want to talk about really interesting things ('go to a fancy restaurant') but others basically clam up ('can't afford it')?
Over the last decade and a half, my personal 'wealth' has been created from finding and maintaining varying interests. Most people I talk to don't seem to have any. They work/play, spend/earn, watch tv, listen to music and go out with friends to bars/clubs. And when you ask them about their interests, they rattle off the list I just made. I suppose it has to do with the idea that education is something you're forced to deal with and 'luckily' it's over after college.
Finding those (IRL) who have interests or who believe in lifelong learning is like finding a needle in a haystack.
