After a bestselling book and new Netflix special, Marie Kondo has tens of millions of people around the world organizing their homes and businesses. The key to the methodology is not minimalism but mindfulness. It is asking yourself - does this procession “spark joy”? If the answer is yes, you neatly put a trifold in it and put it in your drawer or closet in such a way that you can see it. If the answer is no, you thank the object for its years of service and then promptly donate or trash it. Banks should do the same thing.
