Why the usual cleanup doesn't stick
Almost everyone has done that big Saturday cleaning, with loud music and a full trash bag by the end of the day, only to watch the mess come back within three weeks. Marie Kondo uses this repeated failure as the starting point of the book: tidying a little at a time, room by room, doesn't work because you never see the real volume of what you own.
The problem isn't a lack of motivation or a lack of shelves. It's the wrong method. Without sorting by category and without deciding what stays before thinking about where to put it, the house becomes a game of shoving stuff from drawer to drawer, never really solving anything.
That is the promise behind the book's title: if you follow the right order, tidying stops being a chore you repeat every week and becomes a one-time event, done once in your life with care, without having to start over from scratch.
