I am an outlier here. I pay it within a day of charging something. Reason is I used to have a cc problem. Had 30K in cc debt, was paying ridiculous interest, would pay 1K and family would charge 900 and a few hundred in interest and it just kept rising.
Then I found MMM. I took out a TSP loan, paid off the cc debt, put a block on them, and only used bank card for everything, and started to aggresively pay off the TSP loan 2K per month and then some. We stopped using all cc for about a year, just couldn't be trusted to even use just for the cash back. We also stopped spending like drunken sailors.
Only now am I comfortable having cc's and want to sell tradelines eventually. So I got a few cards and have to spend $500 in 3 months and will get $150. So I buy groceries on the cc's and go home and pay the bill. I just still don't feel comfortable having a cc balance at all. I feel like we will think we have money and spend and then the bill will come and we won't have the cash--that's what used to happen. Now that I found MMM, that is defintiley not the case and we have plenty o' cash, but I just can't shake the feeling.
