I talked yesterday about sorting through random paper. Work more on this task today. Don’t touch a piece of paper in your stack more than one more time. Handle whatever it requires, and discard it. If you can’t handle a particular task now, put a note on your calendar to follow up on it or research whatever it requires at a later date. And if you absolutely need to keep the piece of paper, put it in a single folder. Then revisit the folder weekly to ensure that you haven’t neglected any tasks that need to be handled. For example, I keep flyers that I receive for new roofs, new back-up generators, new bathrooms, etc. Those go into a page protector and into my three-ring binder. We likely won’t need any of these items next year, but when we need them or want to pursue them, I have them.
Time required: Depends on how long you have/give to work through any paper stack you may have. As is typically the case, your mileage may vary!
