Decluttering does more than remove physical clutter—it can actually make your home calmer—and there are ways to make it easier. Some organizing pros recommend waging a whole-house war on clutter to knock out the excess stuff in one fell swoop, so no room remains untouched. This approach may take a whole weekend (or even longer), but it might also be more successful—and it’ll mean the chore is finished quickly, not left to drag on for months and months. Decluttering the whole house can also be broken down room by room, so it feels doable. A few new organizers or clutter management tools (think bins, crates, shelving systems, and the like) are suggested but not mandatory. Ideally, at the end of the decluttering process, there’s not much left that needs to be stored, but a little extra equipment can help tame whatever remains. To use this room-by-room guide to its fullest potential, gather a trusty team—the whole family, ideally. (After all, they helped create the mess, right?) Give every family member a room to declutter, or work as a team to declutter one room at a time. This way, everyone will have buy-in on the success of the decluttering project, and will hopefully do what they can to keep spaces clutter-free for years to come.
