Another in a series of thoughts on decluttering and belongings, the French culinary specialists have given the world mise-en-place, or everything in its place. And the principle extends beyond the kitchen. When I lived in my small home, I tried to adhere to this principle to maintain my sanity (with mixed results).
How far you take it is up to you. Maybe the bookshelves keep a clean and orderly appearance.

Or you meticulously organize your pantry.

On the other hand, maybe you’re lucky if everything fits on a shelf. 
Whichever side you currently find yourself on, remember that it can be better. Find a home for everything – one that looks pleasing to your eye. Then, make sure every item returns to its home after use.
If you don’t have room for everything, then that’s a discussion for a later time.
