Those of us who write know that in order to overcome the blank page, we need an idea. Essentially, the idea is the FIRST PART of the writing process.
But an idea is truly just the beginning. When the project (book/story) is done, the idea HAS to be fully developed. As a writer, it is crucial to breathe life into the idea by populating the landscape of the story with vivid characters, great settings, inciting events, and a resolution.
Erik Bork has a written a wonderful book, The Idea. I gave a copy away several weeks ago, and the woman who received it was so excited. She read the book and evaluate her own writing and saw where she was ‘skimming over’ the basics of developing the idea.
So, before you write a single word, you need to take the time to evaluate your idea. Will this idea support a full story? Can you build a plausible plot around the concept? Will the Protagonist of your story carry his mission to fruition? More importantly, can you define his mission?
These are the kinds of things to consider, and I strongly you read the book, The Idea. I know it has helped me tremendously.
