Habit Changing Week

When I write a book, I have generally thought about the book in a general way for months. I have a plot point list to keep me on track and keep the book from sagging too much in the middle. I start on page one and write until I can type "The End."
This has worked for me for six novels. It is comfortable. And flawed.
Mistaken Promises, the third in the Hazel Whitmore series, will not write this way. Every few chapters I come to a stop wondering where to go next. There is a plot point list. I have thought about the book and know the general idea of the book. And I come to a stop wondering where I go next.
It is on bullying. The person doing the bullying has a reason and is desperate to hurt Hazel for this reason. One scheme after another falls apart. And I ran out of schemes before running out of book.
Dead stop. Blank mind. Frustration.
So I tried something new, something I never do. I knew what the climax of the book was going to be. I wrote the climax scene.
Now I know the next scheme. I can fill in the time from the former dead stop to the climax.
Then I can finish the climax, the denouement and type "The End."
