Just because you have a poor credit history doesn’t mean you can’t get credit. Creditors set their own standards, and not all look at your credit history the same way. Some may look only at recent years to evaluate you for credit, and they may give you credit if your bill-paying history has improved. It may be worthwhile to contact creditors informally to discuss their credit standards.
Next, estimate your monthly spending habits for other expenses such as gas, groceries and entertainment. Create a limit, based on your income, of what you can spend in each of the different categories of expenses. For example, if you tend to spend $400 a month on groceries, try to stick to $300 a month on groceries by making changes like buying generic brands, using coupons, and resisting impulse purchases.
