Here’s some science that supports getting rid of clutter to free your brain for the task at hand (literally).
“The brain constantly keeps track of whether objects are within reach , and simulates movements that are feasible to manipulate the immediate environment, even in the absence of any intention or explicit goals [22,57–59]. “
