So many people say never do this and never do that when going about and giving advice to authors. But, except for extreme examples of stupidity (disjointed plots, rampant spelling errors, glaring contradictions, etc.), for every one of these “don’ts” which supposedly make stories unpublishable I can find examples of these “don’ts” being used in published works by both established and new authors all the time.
So how did these “don’ts” come to be “don’ts” then? Who knows. Maybe it is just another example of a lie being told often enough that it becomes truth.
