I heard it said that there are basically three kinds of writers:
1) Those who plan everything to the Nth degree
2) Those who wing it
3) Those who fall somewhere between the two extremes
I’m a three leaning towards two, I did try writing out a plan for I think the Landfall Campaign but then once I started writing, never remembered to refer back to it. What I do have for each work is a set of mental notes in the form of key scenes. These might be battles or a brief conversation, either way they’re important points for the creation of the story. I like to think of it as an incomplete alphabet. When I know I have A, B and D, I know have to go through C to logically get from B to D. It helps break huge looming task that is book writing down into more manageable lumps while at the same time keeping at eye on the endgame*. There is no such thing as a one perfect method of writing that works for everyone – no matter what people who are usually trying to sell their ‘perfect’ method claim – what there are is a number of techniques and what you have to do is find the combination that works for you.
*Quite a few of the early Discworld books by the late Terry Pratchett were chapterless and I don’t know how he managed that.
