Tidying Up was easily the best self-help book I read last year (and I read a lot...mostly stuffy business topics and meditative personal growth), but I so much enjoyed its Life-Changing Magic that I recommend it to friends and family constantly.
I'm not sure this post is entirely relevant to design or development except I can say, when you have a lot less bullshit around you, you have room to think. Space to think means space to tap into that creative rhythm, solve the world's problems, or at least not waste 45 minutes rooting around for your favorite size of Micron pen because you thought you put it in the left drawer of your desk where you usually keep the set, but instead found it in a pencil bag shoved in the back of your closet.
I spent about a month following the KonMari method from top to bottom through my house, decluttering then organizing, and it is life-changing. Her method does align quite a bit with UX because everything has a proper and logical place; the experience of using the space of your home is improved.
Spoiler alert, if you have not read the book, the basic premise is evaluating every physical thing in life and asking yourself, "Does this bring me joy?" If it does, keep it; if it doesn't, get rid of it. That's it.
One of my favorite chapters is about decluttering your wardrobe:
"The socks and stockings stored in your drawer are essentially on holiday. They take a brutal beating in their daily work, trapped between your foot and your shoe, enduring pressure and friction to protect your precious feet. The time they spend in the drawer is their only chance to rest. But if they are folded over, balled up or tied, the are always in a state of tension, their fabric stretched and their elastic pulled."
Oh, and I completely do this with my socks now:
Lay the socks flat and roll them up like sushi. Place them snugly in your drawer.
