How did you generate income during college?
joe_bleau: Bought and resold used textbooks, undercutting the campus bookstore.  Bought electronics parts and test gear at hamfests, dead freight sales, and from profs; resold what I didn't need to local surplus dealers (really have to know what stuff will sell).  Had a total blast as an experimental subject (economics and biology).  Teaching/lab assistant during the school term, research assistant during summer.  Repaired, upgraded, modified, and installed home and car audio systems for classmates and profs.A classmate cut hair (which was almost certainly illegal, in retrospect...).  Easy gig, and he had all the business he wanted right there in the dorms.Heard rumors that someone would buy a car at each break, drive it out to school, and flip for a profit.  His angle was that the cars were salvage titled imports that had been rebuilt, and his home state allowed title washing, or something like that.  I think the DOT closed the loophole that he was exploiting.
