My roommates call me a neat freak, but I really don't consider vaccuuming the apartment once a week, or cleaning up the kitchen so there's no food on the counter as such.
Organization. Well, depends. If I'm stressed, things get cluttered. But when I want to procrastinate, I clean. I'd almost call it a vicious circle, except cleaning's good
Generally though, I tend to have a lot of things on my mind, and a lot to do. So I write to do lists. When you're knee-deep in work, crossing something off a list is a great feeling.
