Prose is architecture, not interior decoration.

– Ernest Hemingway

The story is something which builds on it own taking its own time and path. All one has to do is to find an idea for the starters. The rest will follow. Focusing on the idea and developing is all that matters. One's imagination will lead to the end part of the story. Use your imagination and describe it in the best words you find. Be involved in the story. Feel it. Go along with it as if you're one of the characters. Make a connection. 

Bam! there is your story.
