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.
