I will be hard to pay it off if you have a big balance already, but try and not to use it and start paying it off, you will feel better when you do and it will free up more money to use as cash and a little extra to save away. Contrary to what the banksters say they DO NOT want you to pay your balance each month. The interest is their cash cow. The banksters refer to people that pay off their balance each month as "Dead Beats" because you get to use their money for free for 30days and that drives them crazy.
One way we as a nation could stick it to the banksters would be for more of us to pay off our credit cars and pay them off each month and only use them once and awhile. Paying with cash helps out the little business man and the mom and pop stores. The biggest weapon we have against the banksters and "The Man" is our wallets and pocket books. Spending less and saving more (think credit union) will starve to beast. The banksters here and around the world have tons and tons of debt on their books and that is the bubble that is getting ready to break. They have more debt than us little people have (although our debt feels large to us.) and with us not using our credit cards and paying off our balance each month that mountain of debt will hurt them. This could a death of a thousand cuts for them if we do it.
