A very large part of organizing is relocating items. Items that get taken out and need to be put away. Things that end up in the incorrect space or room. Even though I practice the "OHIO" method (only handle it once), I still have to relocate items at times.
Take for instance, groceries, most people unpack them in the kitchen. This makes sense because this is where most of them get put away. Grocery items also end up the overflow area and bathroom area.
I have found that people with multiple levels dwellings struggle with this all the time. I have found many piles on the stairs (to go up or down).
So anytime you go from one room to another or another level, make sure you have something in your hands that needs to be relocated! Save time and steps!
