One of the key organizing tips I can give you is this, “Don’t Put It Down, Put It AWAY!”
When you’re coming in from the car or going from room to room, don’t set things down, they tend to stay where you put them and grow!
Everything should have a “home.”
Everything should “live” somewhere.
Wherever that home is, take it there immediately, or at least by the end of the hour or day so that piles don’t start growing and get out of hand into heaps and mounds.
