Albert Einstein, as famously disheveled as he was brilliant, quipped, "If a cluttered desk is a sign of a cluttered mind, of what, then, is an empty desk a sign?" While he'd clearly taken to heart the grammar rule against ending a sentence with a preposition, Einstein was more of a rule-breaker when it came to organization. And he got a lot accomplished, so clutter must be an OK work environment for the rest of us, right? Well...not so fast.
