That's 100% true. After a certain point, I migrated from using my "bills" checking account for everything to using a credit card with cash back rewards, and paying that off every pay period rather than using the checking account. But, that is only useful advice if you are already out of debt - if you're carrying a balance on your credit card, rewards are likely not going to out pace your interest accumulation. It's also a good idea to try to fit in as much savings as you can - any little bit in a money market account making you money is a good thing, and invaluable when an emergency comes up. But again, that is very very dependent on your financial situation, and may not be realistic to many people.
