Brian,
Being a Marine helped me with not accepting "piles." I either put items in their places as soon as they get home or immediately find a spot if there isn't already an assigned area. It's just a lot easier to have the, "everything has its place and every place has its thing" mentality. Less work in the long run.
My friend on the other hand finds the first empty horizontal surface. If it's the garage floor where a car normally gets parked, he doesn't care. If it's the kitchen counter and garage items, they will be there for years. He claims to know where his "piles" are located but frequently purchases items he owns because he's not organized.
Saying that, I know neither of us will ever change. Organized folks seem to stay that way and those who pile tend to stay that way. Good luck on cleaning up in the next few weeks. It's always good to at least clean all the piles up every once in a while and situating items so you don't keep acquiring identical items, especially expensive woodworking items/tools.
