The following are Murphy's Laws and Corollaries relevant to planning and strategy: 1) "Anything that can go wrong will go wrong" or "If something can go wrong, it will" or "things will go wrong in any given situation, if you give them a chance," or more commonly, "whatever can go wrong, will go wrong"; 2) "Everything takes longer than you think"; and 3) "Nothing is as easy as it looks".

Murphy's Laws are common adages, observations from life. Murphy's Laws codify the apparent perversity of the Universe and the need to plan and be prepared.

Murphy's Laws may sound light-hearted, but they should be remembered.

Thank Murphy and his Irish humor.
