Storytelling is in the details. Most stories when broken down can sound just like any other story. “Girl meets boy. Events happen. They fall in love. They live happily ever after.” “Life is good. Bad event happens. Battle ensues. Someone prevails.” “Life is ordinary. Something is discovered. Events take place. New inspiration is found.”
Details breathe life into a story. Building characters and the world they live in is a painstaking process. Authors detail every aspect of what makes that character do what they do, react the way the do, think and feel they way they do. Those details don’t always get written into stories but they exist on scraps of paper, old files, mental images, etc. And when a writer has done their job well, the character they build becomes as real to the reader.
