i know $7k isnt that bad, but to me it is bad. im not the type of person that like to owe anyone money, this is the reason i dont have a ton of mods on my car and why i have yet to finish school. at the moment, my current debt is about $300 total. you just have to be smart about the way you spend.
as mentioned earlier, if you want to buy something expensive, save up for it. if youcant wait that long, then open a credit card with one of those 0% intraductory rates and pay it off before it passes the trial period. i always shop for deals. im not saying go and buy cheap s***, just be smart.
for example, i wanted to upgrade my entire car audio system. i looked around and found what i wanted. when i went to tweeter, i applied for a tweeter card and was approved, but i didnt buy anything right away. a few weeks later, i got a flier saying "cardholders get no payments and 0% for 12 months." i blew a couple thousand, but instead of making no paymentsduring that twelve months, i divided the total by 12 and made monthly payments so that it would be payed off before the end of the no interest promotion.
my advice is to stop buying stuff for your car IMMEDIATELY!!! then, as rktktpaul said, chop away at them starting with the card that carries the highest interest rate. it will take a while, but it is the best way to do it.
