Oh gawds, yes. I have our household expenses estimated in my head and constantly adjust for when there might be some extra money or, if we’re going to be short. I’ve got printed out lists I scribble on, updating constantly. There’s no need for me to wonder how much money gets left in my checking account because on payday then everything’s already designated out, if there’s more than $50. left then that gets transferred to savings to await the next unforeseen disaster or forgotten bill. ARGH!
