I call it the never leave a room empty handed rule. As you go in and out of rooms, you make sure your hands are never empty. So if you see a toy or toys you pick up enough that you can carry in that one trip, take it to the room it belongs, and then once you arrive in that room as you see something in there that shouldn't be there, either trash, or dishes, or dirty laundry, you then pick it up and take it to the room where it belongs, then so on and so on. In doing this you are saving a lot of time and energy just picking up and cleaning the house while you were already in that room. I have 3 kids all under 10 and this makes my life so much easier and saves me so much time.
