Decluttering fails when it is treated as a one-time event rather than a system. Most people sort their belongings once, feel good for a week, and find themselves back to clutter within a month. The reason is simple: the underlying habits and systems have not changed.
The Cozideco decluttering framework works in four stages.
Stage one is a category audit. Go through your belongings not room by room, but category by category. Clothing first, then books, then kitchen items, then everything else. This prevents you from moving clutter from one room to another.
Stage two is the three-box method. For each category, create three groups: keep, donate, discard. Be ruthless. If something has not been used in twelve months and has no clear future use, it leaves the house.
Stage three is a storage system. Only after you have reduced your belongings should you think about storage. Now you know exactly what you have and how much space it needs. Buy storage to fit your items — not items to fill your storage.
Stage four is a maintenance habit. Spend ten minutes every Sunday doing a reset. Return items to their designated places. This is what prevents the return of clutter.
