“7 Ways to Use Brain Science to Hook Readers” is amazing and has so many insights and seems like the roadmap to what you want to achieve with your first chapter. I know that I need to focus more on this: “unless those characters are actively engaged in solving a problem–making us wonder how they’ll get out of that one–we have no vested interest in them.” And being mean to my protagonist.
Also, these three:
“This means that the protagonist must react to everything that happens, so we understand how she’s making sense of it.”
“We immediately need to know the protagonist’s agenda.”
And the “eyes wide shut test” to see if I am being specific enough was a new tool.
