Sit down, grab a calculator, and total it up. If you don't like what you see, you will need to make some temporary sacrifices to accomplish your goal of paying down your debt. List your monthly take-home income and all your expenses, and analyze both. Then, look for areas where you can trim expenses. For example, you might consider dining out less often, renting videos instead of going to the movies, or postponing a major purchase.
Some people can go cold turkey and spend money only on essentials and debt repayment.
For others, modest cuts work better. Whatever works for you, come up with a doable repayment plan and make a commitment to stick to it. It's a good strategy to concentrate on paying off the highest interest rate debt first. An even better strategy would be to transfer your largest, high-rate balances to a credit card with a lower rate. This will reduce the amount of money you spend on interest, which means you can pay off your balances sooner.
