And remember there may be weeks that you don't have the assigned room, which gives you a catch-up week. Do the areas that are most important to you. If you don't entertain overnight guests, for instance, the guest bedroom night not be so important. Or if you can close off the office/library area, even though it would be great for every room in the house to be done, don't worry about the area you can close off. As everyone else said, doing anything is better than doing nothing! Every little bit helps! One thing is for sure...house cleaning will always be an ongoing project. I've never seen one that stayed clean all the time without it's being worked on every day!
