1. Stop buying on credit.
2. Contact your creditors and push to get your interest rates lowered.
3. Balance transfer your high-interest debt to lower-interest accounts.
4. Pay off your highest-interest debt first.
This simple advice presumes you have income. Maybe not enough income, but there's a paycheck coming in steadily, and that gives you some choices.
Another set of tips to try:
1. Change up your eating habits. Do not buy food at the same places, or the same food. Instead, try to work from a budgeted food amount outward. If you have $100 for food this week, what can that buy you, and how long can that last, and how often must you shop, and is food preparation involved?
2. Sell any vehicle on which you are making payments, and buy a used vehicle outright. It has to be in good condition. You have to be reasonably certain it won't beggar you with repair costs. But a paid-for car is usually cheaper to own and run than a new car.
3. Hold a yard sale (or post on Craigslist, which is free) and sell anything you no longer need or want. It may surprise you how little people are willing to pay for your used goods. They may not buy them at all. A good reminder not to spend so much money on buying all that new stuff in the first place.
4. Empty your clothes closets into your suitcases. What you own doesn't fit? Reduce it until it does, and never buy a piece of clothing again without getting rid of a piece. Be mindful of this when you shop for clothing, because it is easy to think you need multiples when the truth is you don't. If your suitcases are full, you have enough clothes.
