<prompt> Human: Hey all. I am a 19 year old college student looking to change from a Discover It Student card to a card with some better rewards. I have had the card since August 2017, but use it pretty frequently. Its currently my only credit card, but I dont really care for having multiple. Should I just close the card? Or would it be better to keep it and make a couple purchases every couple months? Thanks for the help!  <response>: It is better for your credit to keep it open. Since its your only card, simply use it for a purchase every 6-12 months and pay it off in full by the statement date so that it continues building good history for you. Once you have a few more cards and years of history, you can close it if you want without major negative impacts to your credit score.
