Go through the storage space you looked at yesterday and gather anything that can go into recycling. Focus on the visible stuff … save the things in bins, boxes, drawers, and cabinets for later.
Right now, you want to start creating space so you can move around the area without tripping over stuff. If you’re thinking, “I could use that so I can’t get rid of it,” set a limit as to how much you’ll keep. This limit could be a quantity (keep 12) or space-oriented (keep whatever fits on this shelf and toss the rest).
Your goal is to clear space so focus on the stuff that’s out in the open, you can work on the stuff hidden in drawers and cabinets later on.
