I am a discovery writer. Despite some interesting experiences in the last few weeks, I tend not to do well with pre-planning, extensive outlines, detailed character biographies, and most else that doesn’t involve drafting and revising.
I should qualify that a little bit. I think that there’s a continuum of writing styles, from the heavy outliners to the discovery writers. Most people will hover about the middle half of that continuum, where they like to do a little bit of planning a head of time, and a little bit of figuring it out as they go.
The “figure it out as I go” part of the scale is where I feel most at home. In 2008, I abandoned my first NaNoWriMo idea (which I had done a fair bit of planning for) and started an entirely new novel with different characters, setting, plot, and genre on November 3rd. I still won that year and not only was it a blast, but it was one of the better novels I’ve written – in fact I’m revisiting a lot of the concepts in it for this year’s NaNo novel.
On the other hand, this doesn’t always work so well.
