We have a small house. Over the weekend I was at my SIL's house, also a small house.
What a difference! When I compare how our houses are set up, I can truly see the benefits of decluttering.
(1) We each have about 3 feet of food preparation space on both sides of the kitchen sink. I try to keep mine totally clear (no toaster, blender, canisters, etc. setting out). You couldn't fit as much as a coffee cup on her counters (they eat out a lot, LOL).
(2) I'm trying very hard to keep horizontal surfaces clear (I'm fighting my family on this one) but my SIL has every horizontal surface stacked high.
Seeing what a difference it makes keeping things out of sight really made my continuing efforts seem worthwhile.
