I like the idea of a spend nothing month- figuring out how to make do with what I have, and really thinking about what a necessity is. Of course, it's not really practical (or possible, depending on your situation) to spend absolutely no money, bills will come, and we have to eat, but for the month of january we're going to spend as little as possible. We'll get our milk delivery, and set aside a small amount of cash for groceries that we need- and once it's gone, it's gone. The idea is to really consider where you're spending your money, and whether it is improving your life enough to be worth the cost.
There's one SIL weekend planned that I'm not counting (though I'm going to be careful with expenses that weekend).
Kind of a cleanse for the budget and the influx of stuff (most of it wonderful and much loved) at Christmas.
Anyone want to try it too?
