Thanks to Heartsong for her great tip in the comments yesterday. Yes, absolutely, when something has been on the top of your to-do list for long time and you keep putting it off, you need to either find a way that it can be permanently off your list or get started on it. Sometimes those first 15 minutes are all you need to overcome the entropy.
Today, look for the physical manifestations of the not-yet-done items on your list. What is clogging up your space that doesn't need to be? Do one thing today that cleans some of that stuff out of your life.
The other day Joe & I went and sold books & CDs to Green Apple and that cleared a bit of room, but I still have quite a few things piled up in there waiting to be dealt with. First on my list, though, is not the stuff in the guest room or the basement, but that stack of bills, receipts and mail. It'll be gone by tonight.
