Marie Kondo (Konmari) had a bestseller in the NYTimes called "The Life-Changing Magic of Tidying Up" in... 2010. Wow, I can't believe her book came out that long ago! Lots of useful fun ways to do things in there, which aren't as obvious to non-Japanese people because many of them stem from Japanese cultural values.
It came out so long ago that she has now had a family and given up on trying to keep things neat and tidy!
> The KonMari Method is a simple but effective tidying method, ensuring you will never again relapse to clutter.
