I have VERY few extracurriculars, how does that hurt my college application chances?

I only have like 36 hours of community service as well, none of it looks that impressive. However I have a 4.0 GPA, a multitude of AP classes, a very high SAT score, a great essay, and near perfect academics overall. I'm not that social, so mostly I just read books and study, hence the few extracurriculars.
