I finally purchased a mail sorter -- now I don't have to step on top of my mail that is "organized" on the floor by my desk. And, I realized that I don't need to have all of my files within an arm's length of my desk.
Actually, I've been wanting to put my files in boxes for quite some time -- but I couldn't bring myself to purchase the boxes. During a weekend trip to Lowes I discovered the box you see in the picture -- they're about $1 each. They're a great size -- and -- you can't argue with the price!
Organization -- it's a "lovely" thing! :-)
