Speaking of organization and reorganization: ... how can you organize your life, if you have no clutter? The one requires the other. It strikes me that the more clutter you have, the greater is your potential for leading a life of organization. Therefore, to make your life simpler through organization, clutter it, first.
I recommend auctions. We re-clutter our lives on a regular basis by that means.
Wine-making offers an example of this principle. To make wine you need a certain amount of equipment. In our case, we pick up vessels and bits of equipment in a piecemeal manner, often counting on chance opportunities to arise at garage sales and auctions. As a result, our winemaking has happened amidst a burgeoning chaos, requiring odds and ends of this and that, scattered here and there through the house.
Gradually as we picked up more equipment (clutter) and know-how (mental clutter) we managed to better use our space and our hours (organization). Organization is impossible without clutter.
I am not saying we have reached an optimal situation. The optimal situation would call for more clutter than we have accumulated, as of yet.
