<prompt> Human: Hey guys,Im currently 21 and I just got my Quicksilver One card raised from 500 to 5,500. I have a credit score of 720 and have never missed a payment I have only about 2 years of credit history. What should my next move be with this credit limit raised? I only spend 200 a month on the card because of my low income as a student. Should I get another card or just keep spending like how I normally did with my initial 500 limit?  <response>: Change nothing, keep up the good behavior.
