I can't say about High School, as I went from there into the military, but later in life, after several years of factory/warehouse type jobs, I got fed up and went to college.

I initially went to a community college, and the guidance councillor there tried talking me out of going a Physical Therapy degree route (switched several times and ended up going CS) into a Trade direction instead. The only thing keeping me from regretting the decision is the fact that I'd never had met my current wife if I hadn't gone to university.
