There’s an organizing box called the Homebox… it looks useful.
From the web site:
Owner Jodi Sinden organizes everything within reach. While researching the Homebox, she helped de-clutter hundreds of households, thus learning first-hand how bad the problem really is. One thing she knows for sure: the average household has at least one shoebox with Really Important Stuff in it that nobody knows exactly where it is.
Prior to starting the company, she spent another life working in international development and commerce, helping to organize (of course!) trade missions, a world summit and really big scavenger hunts. She attended a grand total of six universities, and holds a degree in economics, which, since the advent of the Homebox, she knows exactly where to find.
