"Ignore all rules" is a rule to set other rules aside.
In 2001, Stephen King made "ignore all rules" the second rule of reading in his autobiographical On Writing.
"Ignore All Rules" is a rule of the English-language open content encyclopedia, Wikipedia, and also some other localized editions of Wikipedia. Its formulation is generally (emphasis in original), "If a rule prevents you from improving or maintaining Wikipedia, ignore it." The philosophy or mantra was championed by Larry Sanger (a co-founder of Wikipedia, active 2001–2002), who made it the first of a set of site guidelines (but later rejected it); it continues to be disseminated by Jimmy Wales (the still active co-founder of Wikipedia).
