“When I was a grad student, I rented a room in a big house where 11 other people lived, paying $350 a month, utilities included. My room had two twin beds, so I sublet the second bed to another girl and charged her $230 — meaning I was only paying $120 in rent. That was back in 2000. I also allowed myself just $20 a week for groceries, so I was saving more than $700 a month out of my $1,060 stipend.”
