When I start writing, I first have little movie trailers running through my thoughts. I see the funny bits or sometimes the moments that are leading up to all hell breaking loose right before the climax. I never know the whole story until I start writing, then as I get closer I figure that part out. I don't have massive outlines. I don't know who all the characters will be or what their personalities are like. And I think I prefer to write this way. I like the story unfolding as I write and not knowing every detail before I start. I find, for me, the lack of knowing all the pieces is more entertaining and holds my attention.
