When your environment is cluttered, the chaos restricts your ability to focus. The clutter also limits your brain’s ability to process information. Clutter makes you distracted and unable to process information as well as you do in an uncluttered, organized, and serene environment.~ Erin Doland from, https://unclutterer.com/2011/03/29/scientists-find-physical-clutter-negatively-affects-your-ability-to-focus-process-information/
My personal experience agrees. Having spaces set aside for whatever-it-is-you-want-to-do pays off. Sometimes that’s a dedicated space. But sometimes it’s a space which has multiple purposes, which I somehow convert when I’m changing uses.
Having a space which I intend to be uncluttered also gives me the opportunity to clean it up and prepare it for the activity. Sometimes I’m just not feeling the vibe I need to begin whatever-it-is, and taking a few minutes to prepare the space — and maybe prepare some coffee too ;) — puts me into a focused and energized mood.
