Wow, this is making my head swim. I not unnerstan what you all are saying. I pay my credit card balance off in full every month & have never carried a balance & been charged interest on it. I have only owned one used car & two new cars; my last car I paid cash for it (I'm now 50). I only have mortgage on our house, will have it paid off in 9 years, 6.0% interest on a fixed-rate 15-year loan. I owe absolutely no more money on anything. Am I not being responsible? Am I doing something wrong?
