If your closets, drawers, cabinets and shelves are all packed full—and you still have lots of surface piles—you've got more stuff than storage space.
Solution: You've got two options: (1) Lighten your load, or (2) Add more storage space. Make sure you're using the space you do have as efficiently as possible. Find hidden pockets of storage between cabinet shelves spaced too far apart, under the hanging clothes in your closet, on the insides of closet doors. Maximize vertical wall space and look for dual function furniture (end tables, coffee tables and ottomans) items that feature storage.
