This advice is excellent!
To this I add,
Writing the ending first. Even if you are a pantser (that is, you write organically instead of through a strict outline) a great many authors kind of know what that final message is. In just one example when in the film version of Wizard of Oz, Dorothy realizes,“There’s no place like home.”
Maybe it is a rough cut and it will be replaced by splendid editing before publication, but the whole book is driving to the final moment(s). It is what every word in the book prior to that point has been leading up to.
