i paid my last $600 off this morning.
i stopped buying unnecessary shit, stopped eating out all the time, and most importantly, made payments -every- time i possibly could. if i opened my bank account online and had $400 left in checking, i'd put $250 into the card. if i had $200 left, i'd put $100. there are a whole boatload of $50 payments and many even smaller.
just start paying and don't stop until it's gone. pay your bills, stay fed, and whenever you have money left over, move it to your credit card. try to make a small payment every couple days. just focus on that damn number and make it smaller every single opportunity you have until it reads "0".
i also made enough during this period to pay for a trip to jamaica in cash. i only make $39,500 yearly so it's not like i'm hauling in bags of dough, but focusing on my credit card debt also had some interesting side effects - like learning money management and learning how to save WHILE paying down old debts.
it got to the point that i found more joy in moving $50 to my credit card than going out and dropping $50 on drinks over the weekend. it's funny, but all that stuff that i just 'had' to buy before ...... it turns out i didn't. imagine that.
