There are two things I really enjoy in the writing process: preparation and revising. Actually writing the draft, not so much.
But there are some things I can do in the preparation stage that really help me when I'm writing the first draft. First of all, I've started using Scrivener, and I'm loving it. It helps me write my novel in small, manageable chunks.
Before we get to that, though, I have to put my novel into chunks. How do I do that? I outline. I keep my outlines very brief and vague so that there's plenty of room for creativity and flexibility. Like this:
a. Dana acts strangely
b. mad at Jayne for keeping the secret
c. Finds box of old letters
d. Mother says grandmother was a witch
I do this for each chapter. Then when I sit down to write, I'm just writing about 500 words for each chapter scene (usually four to a chapter). My brief descriptions give me enough idea of where the chapter is going that very rarely do I experience writer's block (writer's laziness is another issue). But it also still allows my creative juices to flow.
And of course I have a file for my characters, where I include basic stats (age, full name, birthday) and also personal information. This part is so much fun that I often forget I'm supposed to be writing! That would be my one piece of advice to you. Stop your planning and start writing. Just do it.
