I have a bit of a compulsive buying habit. Which if funny, because I also tend to not spend my money at all. It's usually a case of "No, I can do without new shoes, new clothes, any jewelry, oh, but I'll buy this random thing. This is a great idea."
Last year journals were the thing to buy. I believe I bought four. And one of them I consider my best buy of 2013 (to be honest, I haven't written up everything I bought and then chosen it as the best, but I can't think of anything that tops it at the moment):
I love having something to write things on always handy. There were often times when I would write poems on backs of stray receipts, but no more! And anytime I want to write down a grocery list, remember a song or artist that someone is telling me about, or have a drawing contest while waiting for food at a restaurant, I've got the paper handy.
It's pretty adorable too. Cute and functional.
