<prompt> Human: I stupidly racked up over 3,500 on a high interest credit card. Itd started out as financing for a new computer, and of course I didnt pay it off on time and got hit with a ton of interest, on top of some other poor decisions. This was my first real experience with a credit card - I didnt fully grasp it to begin with. Guess I had to learn the hard way.Anyway. I got my act together, buckled down and paid it off in only 5 months. But now what do I do with this card? Its bad for me not to use it, right? Should I cancel it or make regular purchases with it and pay them off on time? It doesnt really come with any perks its a Barclaycard so I dont see the benefit of having it.  <response>: Its good to keep the account active, eventually they will shut it down if you dont use it at all but that will likely take around a year to happen. What Ive always recommended is just using it to autopay your phone bill or any bill and setting up automatic payments for the cc.
