@George,
All the people who did 'dishwashing' or specimen processing in the labs for me turned out swell. One got a phD in biochem from cal tech, one got an m.d./practices in Beverly Hills, one went into tv and newspaper news as anchor and then columnist, and I'm probably forgetting some, ah, yes, another is a dentist, or was last I heard.
I, on the other hand (B.A., bacteriology), didn't go on in school for reasons having to do with life and money until I was thirty, when I took a zillion studio art courses at night for pleasure, and then when I was forty, when I took a zillion landscape architecture courses... well, not really for profit, but for a satisfying work to do.
Land arch turns out to combine landscape art/design and technical aspects, and was something I never heard of when I was twenty-one. I don't regret any of the explorations.
