>I think you're mistaking someone who's happy but ignorant of their mediocrity, and someone who's aware of their own mediocrity

Not really, I don't think people are unaware of their mediocrity, it's just that it doesn't bother them.

For instance I'm not unaware that I am mediocre at the 100m sprint, it's just that it has never occurred to me to be in the least bit bothered by this fact. There's plenty of people out there who are mediocre at sprinting as well as everything else, and are not bothered by their mediocrity along any of these axes.
