I've read where movie-makers start with a concept, then write scenes for the story, which are eventually patched together to complete the movie. I suppose we're talking about "process" here. It is likely overwhelming to start a book like, "page one". My thought process seems to run like this: A. A concept or some ironic condition pops up in my mind. B. Shortly after, key scenes, often dramatic, follow. It seems that were I to write a series of short stories revolving around the key concept and characters, then some or all of these could be patched together in similar fashion. Does this seem like a sound process to you? What is your own procedure?
