<prompt> Human: So Ive received some conflicting information. Some backstory: I owe about 2500 across two cards. I was past due until this morning when I paid them in full.One friend told me that I should always maintain a small-ish balance with my CC companies and pay the interest each month. His reasoning was that if I didnt maintain a balance I wouldnt be attractive as a customer and thus I would run the risk of the CC company dropping me as they werent making any money by having me as a customer.My other friend told me that I should be using my credit cards throughout the month for some regular purchases but to make sure I pay my balance on the due date so that I dont incur interest charges.Im confused now. Whats the group conscience about this?Thank you.  <response>: Pay the statement balance in full every month.Dont leave any small-ish balances.
