My question is similar to the above poster about the missing liberal arts piece. Is it really desirable to find an interest at an early age and then go on to pursue it singularly via apprenticeships, etc? There is that saying about how educated people know something about everything and everything about something. I guess I still have that bias about what I think education should be. I'm not sorry I took a poetry class in college even though my main interest was biology, for example. I also worked in a research lab at my college in a work/study position which seems just as good as an apprenticeship to me.
