Living on a budget is one of those things that everybody should do at least once in their lives.
Clearly, college students have figured this out. They know where all the cheap beer is, what bars do free food at happy hour, and how many weekend meals you can get out of a single large pizza delivered at 2a on a Friday night.
For college kids, frugality is necessity.
And then they get their first job out of college and a paycheck, and it all goes to hell, racking up tens of thousands of dollars in credit card debt, never to be able to take a real vacation ever again.
