A Netflix show about tidying up might not be an obvious hit, and yet, I’m hooked. So are millions of others. Marie Kondo, the author of a bestselling book on tidying, travels around America with the intention of “sparking joy” through cleaning up. In each episode, Ms. Kondo helped restore order in people’s lives and reignited family relationships through her KonMari method. Seriously. If readers are anything like me, you will have cupboards filled with old devices, cables, and boxes, along with everything else. This show gives great tips on how to sort it all, and, more importantly, explains why you should.
