If you treat the credit card like a debit card (only spend what you have) and pay in full each month then credit cards are great. You build credit, gain points, etc. Nowadays you can check your accounts online so you can always know what you owe and you can even pay multiple times per month if that helps you keep better cheshbon of what you really have available.
I keep track of all my spending – bank accounts and credit cards – in a spreadsheet. I have a line in the checking account sheet that is linked to the total owed from the credit card sheet so the bottom line amount available in the bank reflects money owed to the credit card. So I always know what I have available and can always go back and see where all the money went.
