Save money?
Hell, in college, I didn’t have any money to save!
To eat, I’d buy a big bag of dried beans and a big bag of rice and get a brick of USDA surplus cheese (“gub’ment cheese”) from the church food handout down the street. Total cost, about 5 bucks. That could feed me for a month, if I had to eat nothing else. (And I still enjoy beans and rice.)
And yes, I also did the baked potato thing (hint: ranch dressing), and the mac and cheese thing (with tuna if I could afford it). I eventually learned that potatoes tasted better if I sliced them real thin and fried them up like hash browns with a little margarine and black pepper.
I dislike ramen, personally, although I had a roommate who would drain the noodles before adding the seasoning, and then mix in three eggs and cook the mess scrambled. That did make them more palatable.
I rented a three bedroom apartment and then sublet the other two bedrooms to recover all but a small part of the total rent. (This sometimes backfired though, because Sprint was the long distance provider, and back then, they would take up to six stinking months to bill a phone call. I got stuck with some doozies. There was also one semester where I couldn’t rent either room. I’m still amazed I didn’t get kicked out.
I used an old copy of Yellow Pages for toilet paper. (Works ok if you dampen it in the sink first.) Sometimes I’d get access to the janitor’s closet at work and steal a few rolls, but it wasn’t much better.
I bought a bike I knew had been stolen, but it was a Nishiki racing bike, worth almost $1000. I paid $25 and painted it red. Less than the cost of a monthly bus pass, which I then no longer needed.
(Of course, then a year later I got a $100 ticket for riding the bike after dark without a headlamp.)
My TV, stereo, alarm clock, waterbed, lamps, kitchen appliances, curtains, posters, paintings, and various other cool shit were all acquired by dumpster diving. It’s amazing what you can find in a college town at the end of a semester, especially spring semester. (And most of it went back to the dumpster when I graduated.)
