We were watching a show (Jurassic World Camp Cretaceous) recently and in between episodes, they would stop in a very critical moment, one that left you wanting to watch more, to finish that part of the story. This tactic can be used to keep people wanting more and you can also use it on yourself, to get yourself to keep working on something you’re in the middle of. I remember reading some advice that the best place to stop in your own writing is in the middle of a sentence. That way you can pick up right where you left off and keep going where you were going.
