I've finished going through Project: Simplify's Hot Spot #2, Paper Clutter, which for me involved my desk in the closet of our guest bedroom. I forgot to take a before picture (oops!) as I was so excited to be able to see my desk surface that I just dove right in and started making piles. But this pic shows pretty much the quantity of paper I had to go through - not too much.
I made a 'to be recycled' pile, a 'to be filed' pile, and a 'to deal with file'. Luckily when I moved my desk from the nursery into the guest bedroom about a month ago, I went through a ton of papers and so my piles weren't too bad. I did manage to set some hanging files on the side of my desk up to help slow the paper pile build up in the future though - a 'current' folder for my current projects, and a 'to file' folder for when I don't have time to do more than move old bills to my desk.
