I have several answers to this question. I have a trivet that says "My house is clean enough to be healthy and dirty enough to be happy". When it crosses that line, I try to clean. I have also heard it said that nobody goes to a funeral and says "She was a great housekeeper, but they might say she made beaustiful quilts" Several years ago I bought a book titled "Nobody said you had to eat off the floor". Her premise was you won't get it all done. No matter what you do somebody else (probably with OCD) will see something else to be done. Soooo, I do what I can and listen when my sewing machine calls.
