I thought I'd update everyone on my progress. I've gotten the floor clean, but I still have a long way to go! I eventually pulled one trash bag's worth of garbage from the floor. Unfortunately, I got lazy, and many of the things on the floor were just put onto the shelves in the closet, rather than where they should go. I'll have to work on that. :-)
Now that I've got the floor clean, and I can actually walk into my closet, I'm onto my next project: Shoes!
