When in doubt, the rule of threes is a rule that plays well with all of storytelling. When describing a thing? No more than three details. A character's arc? Three beats. A story? Three acts. An act? Three sequences. A plot point culminating in a mystery of a twist? At least three mentions throughout the tale. This is an old rule, and a good one. It's not universal - but it's a good place to start.
Chuck WendigRead your work out loud. Don't give me that look. Read your work aloud. Don't argue. Don't fight. It will help. I promise. I promise. I guarantee it. If you find it didn't help you, lemme know. I will let you Taser me in the face. And by "me," I mean, some other guy who will be my stand-in. Probably some real estate agent or tollbooth attendant.
Chuck WendigIn my mind, only one inviolable precept exists in terms of being a successful writer: you have to write. The unspoken sub-laws of that one precept are: to write, you must start writing and then finish writing. And then, most likely, start writing all over again because this writing "thing" is one long and endless ride on a really weird (but pretty awesome) carousel. Cue the calliope music.
Chuck WendigYou've got all these characters and yet, you're hovering over one character like a fly over a stinky diaper. Realize that you've got a kickass superpower: you can possess and take-over anybody inside the story. With the power of Point-of-View, you can drag us along for the ride. You can shove us into their eyes, their minds, you can force us to piggyback on their experiences past and present. Sometimes untangling a knotted-up tale means looking at it from different eyes: what better eyes than those of the other characters inside the story?
Chuck WendigWriting advice is not the product of an equation. "If you do X, then Y will occur" is false in this instance. "If you name a character John Q. Hymenbreaker, your book will be an instant bestseller" is crazy-talk. Writing advice is not about providing certifiable answers. It is about making suggestions.
