<prompt> Human: Heres the deal: Im 18, still in high school, and i just want a ps4 honestly. I have a part-time job that equates to between 250-400 every 2 weeks. I know just saving is an option, but between helping my mom out with rent, fees that come up at school being a senior is expensive as fuck for some reason, and other random stuff that pops up from time to time, it really isnt much of one. I feel itll be much easier to make this another one of my monthly obligations, just paying the credit card bill for the next couple or so months. Should i go for it, or us this plan not as good as i think it is?Assistant: a credit card is not free money...Human: Thats the part i think i need help with on this. What am i missing, because it seems to be a loan i can pay off on a set fee every month, but, while i hope it is, somethings telling me its not that simple. I understand theres interest as well, but could explain any other bad things about this?  <response>: The interest is the primary bad thing, but it is a BAD thing. Its not so much because of the amount youll pay now the interest youd pay on a few hundred dollars, even paying just the minimum every month, is not going to wreck you for life. It is because, if you start thinking at such a young age that credit cards are used for things you cant afford now but will be able to pay off in the future, youll do that for the rest of your life, and be perpetually in hock to the credit card companies, paying tens or hundreds of thousands of dollars in interest.Do what uaboglehead said: pay your credit card bill in full, every month, no exceptions. Dont spend money you dont have. Credit cards are a way of delaying payment slightly, of providing purchase protection, and of getting rewards, not a way to buy things you cant afford.
