Writing a novel is a tiny candle in a dark, swirling world. It brings light and warmth and hope to the lucky few who, against insufferable odds and despite a juggernaut of irritations, find themselves in the right place to hold it. Blow it out, so our eyes will not be drawn to its power. Extinguish it so we can get some sleep.
-Lemony Snicket, NaNoWriMo Pep Talk, November 23, 2010
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.
Write even more.
Write even more than that.
Write when you don’t want to.
Write when you do.
Write when you have something to say.
Write when you don’t.
Write every day.
