1) Decide on your genre. Think about genres that really speak to you, that move you deeply.
Is this an historical epic? Are your characters real or fictional? Is this a drama? A political thriller? An action/adventure? Is this a mix of romance and comedy? Drama and historical epic? Science fiction mixed with Drama and Mythology?
2) Where did your story originate? Are you the sole author? Is it a derivative work based on other material, such as a book, magazine article, short story? Is the derivative work public record? If not, you have to acquire rights of the living person to write the story.
Maybe this was an event that occurred that you now want to write about. Maybe you “read about this person” and always wanted to write a story, incorporating this person’s story, but fictionalizing it.
Maybe you lived in the arena you want to write about—Journalism, tennis, ballet, medicine, education, the oil industry, the legal profession, politics, art, music. This is good. But if you did not live in the arena you want to write about, you need to start doing research about the arena. As you get deeper and deeper into the research, you will be amazed how inspired you will become. New ideas and perspectives will reveal themselves. You will become knowledgeable and feel that you have the depth to write a story that is believable and “grabs” your audience!
3) Story values within your story idea – Come up with a main character who has those values.
What draws you to that story? What does the story reveal about the human condition? Your main character has psychological needs and moral needs – What are they? What happened to him/her that caused this character to have these needs? What flaws does this character have as a result of his/her psychological/moral make-up? All of this moral structure value system for your story will give it spine and a theme, and the moral structure value system of your main character will play out in the climax. So it’s important to devote some time to this in the very beginning!
