The KonMari method prescribes not just simple tidiness, which removes objects from sight, but the paring down and organizing belongings so that you have precisely what you need, where you need it. There are several basic concepts for the KonMari method. First, tidy everywhere (the entire house) all at once rather than tidying a small bit at a time. Second, tidy by category (for example clothes or books) not by location. Third, bring every item in a category together and discard what you don’t want before putting everything else away. Fourth, and perhaps most importantly, only keep objects that “spark joy” in you when you handle them.
