As I work on my next project, I keep thinking about the best way to structure a story.
It comes down to three things. First, characters have active goals. They take actions and make decisions based on those goals. Those actions have consequences that move the story forward and potentially create new active goals.
It's really the basics, but it's easy to forget about it and write whole chapters where nothing happens. Dunno if that's how everyone does it, but it's always been my approach.
