Cons of the KonMari Method

1. This process may not be realistic for larger spaces or families: This guide is written from the point of view of a single woman in her early 30's who lives in a small flat in Japan.
2. Category sorting may not be as effective if you have a family.
3. Untagging clothes and immediately hanging them in your closet doesn't always make sense.
4. The book doesn't address how to deal with children's toys.

If you're single, or a couple with a small pet in a tiny apartment it may work. But if you're a large family in a larger space you'll have to pick and choose what works otherwise outsource some of the work.
