As far a school is concerned I learned very little that I actually use. As far as college (both times) is concerned I learned some things, but very little that I actually use. Most of my knowledge is either useless or worthless (Comic Book history, Statistical Information, Brainwashing Techniques...). Everything that I learned that is actually valuable I learned "on the job" (Work stuff, How to feed a baby, how to clean up baby puke...)
