On to room 4 of the house. What is something I have seen in my work many, many times? Unopened mail! Credit card offers, grocery store inserts, magazine subscription reminders, car & health insurance, phone & electric bills, you name it and they send it! I highly recommend signing up for the do-not-send-junk-mail list, just as you would the do-not-call list. One site to check out would be ecocycle.org. Another great tip is to utilize automatic online bill pay services. By paying most of your bills online, you will save paper and also save space in your home.
The sort consisted of many categories and piles. 2 large black trash bags full of mail to be shredded went out of the house and into the shredder. This cleared up much more space for the desk to be an efficient workstation again.
After sorting for 4.5 hours we whittled down the massive amounts of mail to small bins like this one. Everything has a home here in the office space and I'll be back next time to work on some more closets and shelves. Keep it comin!
