Everyone has heard of Murphy’s first law: “If anything can go wrong, invariably it will.” But hardly anybody has even a foggy idea of who Murphy was. The search for Murphy’s notebooks led to a garage in Toledo, Ohio; an inventor’s junk loft in Aliquippa, Pennsylvania; and the home of a retired female blackmailer in Sarasota, Florida. It was learned that Murphy had no first name, that he never could hold a job, and that his writings were returned by the post office for insufficient postage. It seems everything Murphy wrote about had some explanation for why things go wrong. Consider a few more Murphy classics: Nothing is ever as simple as it first seems. Everything you decide to do costs more than first estimated. Every activity takes more time than you have. It’s easier to make a commitment or to get involved in something than to get out of it. Whatever you set out to do, something else must be done first. If you improve or tinker with something long enough, eventually it will break. By making something absolutely clear, somebody will be confused.You can fool some of the people all of the time and all of the people some of the time, and that’s sufficient.
