If you put your house in order in one fell swoop, you will have tidied up in one fell swoop. (In Japanese, the term is ikki ni, or “in one go.”) Rebound occurs because people mistakenly believe they have tidied thoroughly, when in fact they have only sorted and stored things halfway. If you put your house in order properly, you’ll be able to keep your room tidy, even if you are lazy or sloppy by nature.
