the more I think about it, I'm not sure that trying to categorise writers as plotters / pantsters / discoverers / architects / gardeners etc is that useful. Even if one is being highly regimented and formulaic about the approach to a story, there's still an element of alchemy involved the because words still have to fall out of your mind onto the page. At that point you have to kind of allow yourself to be led by whatever light or guide is living in your subconscious. That sort of gestalt practice that isn't easily categorisable.
Agreed. Besides, different novels need different approaches.
