What to do?

I'm on my third day off in a row, and now I find myself wondering what to do. There's plenty to do - clean the fish tank, dust, clean the bathroom, etc - but it's just one of those days where nothing sounds like a good idea. Even stuff that should be fun like playing a video game or watching TV just doesn't sound like fun. I hate these kinds of days because ultimately, I'll get frustrated and take a nap. That sounds like a good idea, actually :P
