<prompt> Human: I know a lot of people have rewards cards and are able to use them responsibly, but Ive never really trusted myself to use a credit card that regularly and pay it off on time every month. However, I was about to make a purchase on Amazon when I saw, for the millionth time, their offer for the Amazon rewards card with a 30 sign up bonus. So what would happen if I were to do this, get the bonus, and then cut up the card? I would have one stagnant credit account just sitting there...would this hurt my score?Assistant: but Ive never really trusted myself to use a credit card that regularly and pay it off on time every month.If you arent going to pay your credit cards in full every month, you shouldnt have a credit card.Human: I save plenty every month, I have no worries about paying off whatever I happen to buy on credit I use mine like I use cash. Im just really forgetful.  <response>: Set up automatic payments
