From Neil Gaiman’s 8 Rules of Writing:

“The main rule of writing is that if you do it with enough assurance and confidence, you’re allowed to do whatever you like. (That may be a rule for life as well as for writing. But it’s definitely true for writing.) So write your story as it needs to be written. Write it ­honestly, and tell it as best you can. I’m not sure that there are any other rules. Not ones that matter.” -Neil Gaiman
