Thinking back to my early pre-school, early elementary days, I got lots of unsatisfactory marks for my "needing self-control".

I wasn't asocial as much as I was, uh, dys-social, but that was mostly with respect to the teachers. I wasn't grade-skipped, but I got over that particular problem by second grade. I don't recall having problems interacting with the other kids, in general. I always wanted to skip a grade, but my parents never liked that idea.

I was always much more intellectually advanced than my classmates, while being much less emotionally/socially mature than my age.

I don't recall not enjoying school, but that's probably because I wasn't particularly bothered by the fact that it was easy.
