Pixar’s 22 Rules of Storytelling by DinoIgnacio.
From the webpage:
Former Pixar story artist Emma Coats tweeted this series of “story basics” in 2011. https://twitter.com/lawnrocket These were guidelines that she learned from her more senior colleagues on how to create appealing stories. I superimposed all 22 rules over stills from Pixar films to help me remember them. All Disney copyrights, trademarks, and logos are owned by The Walt Disney Company.
If you find the rules hard to read with the picture backgrounds (I do), see the text version: http://imgur.com/a/MRfTb.
While cast as rules for “storytelling,” these are rules for effective communication in any context.
