I had an uncle who used to say that all the time: "It's only money." Then again, he was a doctor and he had plenty of it!
It's only money, but when it's borrowed it has to be paid back. And you WILL do it. You know you will. Just as fast, and with as little interest, as you can.
Meanwhile, I, too, am figuring out how to do it better next year. I don't like to feel like an old Scrooge, but I do want to be more or less sensible - sensible and generous at the same time. So starting January first I'm setting a certain amount aside each month - NO excuses - to put toward 2012 Christmas expenses. That will at least help.
