Kind of inspiring... but then kind of scary the extreme lengths this guy was willing to go to in pursuit of paying off his student loans.  Most interesting part for me: he went back to school because after a few years of work he could feel that his communications skills were deteriorating.

There was just one rule about his new lifestyle: Nobody could know about it. "I realized it was the sort of mindless gossip that could be spread over Twitter and Facebook," he said. "I didn't want anybody knowing all about it. The first semester was extremely lonely." Geez, poor guy!
