One popular minimalist tenet is “one in, one out.” When you buy something new and bring it into your home, you give away one similar thing. Buy a new dress, give away one dress. That way you never increase the amount of things in your house. I’ve always liked that idea. But since I still have more clothes (and shoes, and jewelry, and books) than I want to have, I’ve decided to try a “one in, two out” system!
