Despite constant efforts to declutter your home, do papers still accumulate like snowdrifts and clothes pile up like a tangled mess of noodles? Japanese cleaning consultant Marie Kondo takes tidying to a whole new level, promising that if you properly simplify and organize your home once, you’ll never have to do it again. Most methods advocate a room-by-room or little-by-little approach, which doom you to pick away at your piles of stuff forever. The KonMari Method, with its revolutionary category-by-category system, leads to lasting results. In fact, none of Kondo’s clients have lapsed (and she still has a three-month waiting list). With detailed guidance for determining which items in your house “spark joy” (and which don’t), this international bestseller will help you clear your clutter and enjoy the unique magic of a tidy home—and the calm, motivated mindset it can inspire.
