Hm, maybe it depends on where you attended college. I usually didn't attend lectures but between assignments, exams, and discussion sections, college was by a million miles the most productive learning environment of my life.

I orient my career around learning but there's always this little nagging "ultimately the needs of the employer are paramount when push comes to shove" that rears it head every once in a while and prioritizes work I'm already good at over stuff I'd be learning by doing.
