Tidy by category, never by room
Marie Kondo breaks with the usual reflex of tidying room by room. That approach fails because items of the same family are scattered throughout the house. The KonMari method requires you to tidy by category: gather all your clothes into a single pile, then sort them in one go.
The order of the categories is precise: clothes, books, papers, komono (miscellaneous items), then sentimental items. You start with what is emotionally easiest and finish with what is hardest. This progression sharpens your ability to decide.
By seeing the totality of what you own, you become aware of the excess you have accumulated and can no longer lie to yourself about your possessions.
Gather each category into a single pile before sorting: it is the visible volume that triggers the realization.
The single criterion: joy
Faced with each object, only one question matters: "Does it spark joy?". Marie Kondo asks you to hold each object in your hands, because your body's reaction is more reliable than reasoning. If the answer is no, the object goes.
This criterion reverses the classic logic of decluttering: you do not choose what to throw away, you choose what to keep. The nuance is essential. It turns a guilt-inducing chore into a positive exercise in selection.
Before parting with an object, thank it for its service. This ritual, inspired by Japanese culture, eases the letting go and prevents regrets.
Hold each object in your hands and keep only those that spark joy: the rest can leave with gratitude.
One single, definitive tidying event
Marie Kondo opposes the idea of tidying "a little every day". For her, tidying must be a single, radical and definitive event, carried out in one intensive period. Gradual decluttering never creates the shock needed to change your habits for good.
Once the sorting is done, assign a fixed place to every object. Clutter comes back only when objects have no home. Tidying then becomes a gesture of a few seconds: putting each thing back in its place.
According to the author, this big tidying event acts as a trigger. Her clients report profound changes in their work, their relationships and their relationship with themselves.
Do the big sort in one go and give every object a fixed place: the clutter will never come back.
