Check out ynab.com (short for “you need a budget”). It’s a budgeting software that helped me get out of debt. It uses the principles of living off your last month’s income (instead of paycheck to paycheck) and “giving every dollar a job” so you know where your money is going.
Doing just those two things helped me find ~$500 in my budget that I didn’t know existed. I could probably save another $450 by cutting some other expenses. Point is, I wouldn’t have known where to find them if I wasn’t using ynab.
Also check out Dave Ramsey. He has people calling in his talk show that are in much worse situations that are able to turn their debt around.
