Willpower is the determination to finish what we start, no matter what. For the cozy mystery, the easy option is to write the end first or at least just after the first act.
For this genre, I find it important to know where you’re finishing up if you want an easier life.
It makes it faster to plan an effective route, choose the best clues and insert them as you go. It’s almost like drawing a map through your Table of Contents–not sure if that makes sense but I see each chapter following the next like a river. All my characters then embark on suitable boats and sail along with various diversions and dilemmas en route.
But having the end in sight helps me pull them (and me) through the rough water of the middle. And when the end is written, I’m far less likely to give up.
Again, like the first chapter, the final chapter may be written and rewritten. But at least it’s there as my safe harbour after a stormy passage.
It bolsters my willpower and ensures I keep going on to the end.
