I believe the first rule of telling, writing, creating, a story-
The most important step is the last one, because unlike living, the destination is the-
Well, I won’t say it’s the most important part.
The climax, the beginning-
The patterns, the themes-
The characters, the villains-
Those can all be the most important parts.
But the ending will make or break a story.
A dissatisfying ending can ruin everything you’ve built, and no ending at all is a poison! It doesn’t matter how much fun the story is, it has to end, if you keep lengthening it, if you keep dragging it on-
Then you will be left with a giant tangled mess that no one ever reads to completion because either no one has the stamina or because the writing suffered as the Author was exhausted by their own creation.
Some stories can only be written in reverse, Tragedy only made possible when everyone knows exactly how the story ends.
Other stories have surprise endings, but even then, hints to how they will end must be littered throughout the work or the surprise is nothing more than a cheap trick.
A repeating phrase, a gun on the wall, a slow spiral of a villain or the arduous rise of a hero.
They must be connected from beginning to end.
So the end must come first.
That is not to say the end must be set in stone, that it cannot be shifted and changed as the story come to life.
A happy ending can become a tragedy as an Author gains more understanding of their characters, and a Tragedy can be dragged from the edge as the characters refuse, refuse, refuse, to allow THAT to be their end.
