There are some creative minds that thrive in a messy atmosphere. But for the most part, there's a high correlation between tidying up and being able to think clearly. Perhaps the outward mess is a visible reminder of the pile of thoughts we haven't sort through, but keep adding more to on a daily basis. Perhaps the clutter in our offices or rooms is the tangible sign of the plans we are procrastinating on. Or maybe its the manifestation of the fears we have yet to face.
Whatever it is, cleanliness helps us tackle the thoughts, patterns, or challenges holding us back because - we can finally see and think clearly enough to address them.
