I'm thinking about going back to school...

Well I know I want to go back, if a finger's bredth away from my BA in Business. Since that is what I want to do it seams apropos.
My dream, my own business, one that makes the rent. Jewelry and art shop seems top of the list of possibilities. I just got some information from the GIA (gemenological istitue of america) about thier business degrees and degrees in wax carving, stone grading, etc. I'm not sure how much of it I need though. I mean they have a course on bead stringing. While I will be the first to admit that it's not "just stringing" once you have covered knoting, weaving, finishing the ends, and what to string on what, (ie really abrasive edged stones on wire, pearls do well on silks, I prefer Nymo for strength, etc) what else is there?
The stone grading does sound useful though. I know some diamond grading, but not much about colored stones, (other the good, medium, bad, I can eyeball which is better and pick out synthetic and lab stones). Gar the other bad part is that they have campuses in California and NY. some stuff can be done online, but not the technical gritty details of mold making, clasp making, etc. I could see about crashing with my aunt in Albany and taking the train in to NY. It would be cheaper then living in the city! hrmmmm...shall have to see. Their might be closer schools, with more finacial aid!
