"Sometimes I'll have a scene that strikes me, I just feel like writing a scene, a mini-story that seems like it might lead somewhere. But that is such a tentative, fishing-hook way to go about it that these days I've found it's easier to kind of at least have your concept and start attaching things to a skeleton. So I try to find the armature, the kind of backbone of it first that you can start to hang those scenes on."
