<prompt> Human: Hey guys, Im a nineteen year old college student and I just got my first credit card with my bank. I have a full time job and I make 12.75hr. I just got the card and its got a 500 limit and my interest rate is freaking 26!! Im pretty good with my money as it is but I would REALLY love some advice on how to manage having a credit card. I know the basics, like dont treat it like extra money, and with that interest rate I know I need more than I actually spend. But I wanna know things like how close should I come to my limit? How much should I pay off every month? And anything else you guys think is helpful. PS. I live at home and my college is completely paid offtech school and I own a car with no payments. If that helps. Thanks for any help.EDIT: Thanks for your help everyone! I really really appreciate it!  <response>: If you wouldnt buy it with cash, dont buy it. Interest rate shouldnt matter. Pay it off in full every month. Utilization doesnt matter unless youre planning to use your credit score in the next month or two. In that case keep it under 30.
