I usually have an idea then talk about to people and when I talk about it I get more ideas for a story. SO then it on its own takes shape. Then when I think I got enough ideas in my head for the story I start writing it down on paper. Then when Im done with that. I type it up on my computer and edit it as I go along. Thats been my best way so far. Then when you film a bunch more ideas go by your head to make.
SO yeah.
