1. The author's original vision for the story. Many authors have a clear idea of how they want their story to end when they begin writing it. This vision may be based on a personal experience, a dream, or simply a creative impulse.
2. The development of the characters and plot. As the story progresses, the characters will develop and the plot will thicken. This development will often lead to natural conclusions or turning points that can serve as the basis for the ending.
3. Feedback from readers or viewers. Authors and filmmakers often seek feedback from readers or viewers as they are working on their projects. This feedback can help the author or filmmaker to identify potential problems with the ending or to make improvements.
4. The need for a satisfying conclusion. Every story needs a satisfying conclusion. This conclusion should resolve the main conflict of the story and leave the reader or viewer feeling satisfied and fulfilled.
The ending of a story is an important part of the overall work. It can make or break the story and can leave a lasting impression on the reader or viewer.
