Emma Coats, formerly a storyboard artist with Pixar, has taught storytelling for a few years, I gather. Her 22 principles of storytelling have been on the Interwebs for a while, but I don’t believe I’ve linked to them here. They are very good.
#4: Once upon a time there was ___. Every day, ___. One day ___. Because of that, ___. Because of that, ___. Until finally ___.
#5: Simplify. Focus. Combine characters. Hop over detours. You’ll feel like you’re losing valuable stuff but it sets you free.
#9: When you’re stuck, make a list of what WOULDN’T happen next. Lots of times the material to get you unstuck will show up.
For a different perspective, award-winning author Paul Harding has a few ideas of what makes fiction work. “Fiction is about immanence. We are beings who experience our selves in time and space, through our senses. Fiction persuades its readers that they are reading something artful by immersing them as fully as possible in the senses and perceptions, the thoughts and actions of fictional lives.”
Author Barnabas Piper also chips in his two sense, saying it’s the boring parts that make the whole story work. “World-class novels are not composed of email responses and traffic jams and grocery shopping. But without such things the characters would never get where they needed to go and be who they need to be.”
