Mistake #4: Leaving your medicine cabinet shelves as is.
And while we're on the subject of bathroom storage, here's one common mistake you can fix with minimal effort. Lisa Zaslow, an organization and productivity expert and the owner of Gotham Organizers in NYC, says she often helps clients who have no idea that they can adjust the shelves in their kitchen and bathroom medicine cabinets. Doing this allows you to then group similarly sized items together; e.g., all small pill boxes can go on one shelf, all tall bottles can go on another. Customizing your cabinets allows you to store more items, more efficiently—and it's usually doable without any special tools.
