Marie Kondo

For low-cut socks that just cover the feet, folding twice is enough; for ankle socks, three times; for knee socks and over-knee socks, four to six times. You can adjust the number of folds to achieve the height that best suits the drawer.

So it’s time to abandon this custom and keep all our clothes ready to be used year-round, regardless of the season.

Categorizing by season—summer, winter, fall-and-spring—or by activity, such as work and leisure, should be avoided because it is too vague. If my client’s space is limited, I have them store only small, specific off-season items, such as bathing suits and sun hats for the summer season, and mufflers, mittens, and earmuffs for the winter season. Although not a small item, winter coats can also be put away in the back of the closet during the off-season.

If you are planning to buy storage units in the near future, I recommend that you get a set of drawers instead. Be careful not to bury clothes in the cupboard even if they are off-season. Clothes that have been shut up for half a year look wilted, as if they have been stifled. Instead, let in some light and air occasionally. Open the drawer and run your hands over the contents. Let them know you care and look forward to wearing them when they are next in season. This kind of “communication” helps your clothes stay vibrant and keeps your relationship with them alive longer.

If there are too many books to arrange on the floor all at one time, I ask my clients to divide them into four broad categories:

General (books you read for pleasure)

Practical (references, cookbooks, etc.)

Visual (photograph collections, etc.)

Magazines

Once you have piled your books, take them in your hand one by one and decide whether you want to keep or discard each one. The criterion is, of course, whether or not it gives you a thrill of pleasure when you touch it. Remember, I said when you touch it. Make sure you don’t start reading it. Reading clouds your judgment. Instead of asking yourself what you feel, you’ll start asking whether you need that book or not. Imagine what it would be like to have a bookshelf filled only with books that you really love. Isn’t that image spellbinding?

Let’s face it. In the end, you are going to read very few of your books again. As with clothing, we need to stop and think about what purpose these books serve.

The moment you first encounter a particular book is the right time to read it. To avoid missing that moment, I recommend that you keep your collection small.

My basic principle for sorting papers is to throw them all away. My clients are stunned when I say this, but there is nothing more annoying than papers. After all, they will never inspire joy, no matter how carefully you keep them. For this reason, I recommend you dispose of anything that does not fall into one of three categories: currently in use, needed for a limited period of time, or must be kept indefinitely

Limit yourself at first to sorting papers that give you no thrill at all and finish the job in one go. Letters from friends and lovers can be left for when you tackle sentimental items.
