The first one is obvious, stop using your credit cards.

Second, consider consolidating your credit card debt onto one card - or moving a balance from one card, to one with a lower interest rate.

Third, start making double payments. If the calculated minimum payment is only on the accrued interest, then you need to make a double payment to hit the principle of the debt.

By finally hitting the principle and discontinuing use of the card for purchases, you'll see that balance begin to drop.
