Parkinson's law, which provides insight into a primary barrier to efficient time management, states that, "work expands so as to fill the time available for its completion". This articulates a situation and an unexplained force that many have come to take for granted and accept. "In exactly the same way nobody bothered and nobody cared, before Newton's day, why an apple should drop to the ground when it might so easily fly up after leaving the tree," wrote "Straits Times" editor-in-chief, Allington Kennard who continued, "There is less gravity in Professor Parkinson's Law, but hardly less truth."
