<prompt> Human: I only use two credit cards. I know its considered good to have a lengthy credit history but I think most of these cards are only a year old anyway. I use the mint app to monitor my credit. Any other tips I need to know?EDIT: Thanks guys. Turns out, 811 are from student loans. 2 are the cards I actually use and one is from best buy.
