Another practice that is helping is to go paperless as much as possible. Do I really need the original or can I scan it and keep an electronic copy. Do I really need to keep the item at all? Really?
What's helped me get through these boxes of documents has been asking this question - did I even know it was in this box? Have I thought about this item in my hand? No? Out it goes.
Why didn't I think of this sooner?!
I'm sure no one else can relate. LOL
