Use your savings from living at home toward that goal — buying a home, paying off student loan debt, or socking away retirement money while you can make the most of compounding.
Hahaha this is the stupidest advice. You need a thing called disposable income in order to have savings. The idea that someone working 25 hours a week a Target while living at home is going to be able to have anything left over for "savings" after food and car payments is ridiculous. Nobody on IBR is thinking about how to sock away extra money towards their loans... hell, that's the purpose of IBR. And anybody financially able to save for retirement or a house while living with their parents is probably already living with their parents for that exact reason and doesn't need this advice.
I've thankfully never got to the point that I had to move back in with my parents, which I saw as a pit that if I fell into, it would be very hard to escape from again. That would have been in New Jersey, as it turns out, where entry-level job pickings are slim, so I would have had to come up with enough money all at once to not only get my own place, but also to relocate.
