In my kitchen, I labeled all the shelves with what went where. Basement storage was also labeled. Office drawers. Even my bookshelves. All designed to remove that second of thought that would often suck me into a vortex of overanalysis when I was trying to remember or decide where something should go, and at least give me a general idea of where to look when I needed some item.
I am also a big believer in printed file labels, organized by relevant categories. For a simple example, even just having alphabetical hanging folder labels, with individual file folders for client names or project names gives the brain one less place to wander.
