Professional organiser Marie Kondo recommends focusing on one category at a time in the following order: clothes, books, papers, 'komono' (miscellaneous items) and then sentimental items. You don't have to follow Kondo's categories to the letter; instead, you can use her method as a guide for creating your own.
Start small, like decluttering a single kitchen drawer, to build momentum. Our favourite starting point is the underwear or sock drawer in your bedroom. There’s something so satisfying about sorting through and folding smaller items. Once you’ve done the underwear drawer, you’ll feel a sense of accomplishment and be more willing to declutter a larger area, like your wardrobe.
