Simply set it back to 1972, and program as usual. The days of the week in 1972, were exactly the same as Year 2000 days. There is no escaping this menace. Lurking behind doors, exploding from drawers and multiplying on shelves and counters. Clutter is wasted space, time and energy.
Clutter is really just stuff.
Stuff you don't want, don't need, shouldn't have. It's cluttering up your life and your mind, seriously inhibiting your ability to be organized. It is virtually impossible to get organized without first tackling this problem and, once it is done - oh, it really is so much nicer. It's not important whether you are able to dedicate a large block of time for a room or just 5 minutes for a drawer. What matters is getting the job done.
