I think it's pretty frustrating being an outlier in any dimension. Your specific needs are always ignored. Being smart is no different. At least when I was in school they were always like "eh he'll do fine, let's concentrate on the borderline dunces".

When you leave school you can find your level a lot easier - go to a university and get a job where other people are at the same skill level. At least that's what made me happier after leaving school - I didn't have to mix with stupid arseholes.

It wasn't until I had kids and was suddenly thrown into a roughly random selection of 30 people that I remembered just how few of the general population I have anything remotely in common with. School sucks.
