Clean?

Some people dust every Tuesday, laundry on Wednesday, baking on Thursday, etc. Everyday has it's chore. How do I know when to mop my floors? When I vacuum and they still look like a herd a buffalo went by, it's time to mop my floors. I do laundry when I run out of clean underwear. When the dust bunnies are bigger than Asa, I dust. When it is nice and sunny outside, forget everything I just said.
