You mentioned in an earlier answer that learning to revise was one of the biggest factors in making your work publishable.
Would you give us an idea of the process you go through when you revise?
Thanks for the question, Isaac! (Isaac, by the way, is the person who introduced me to my wife and set us up on our first blind date.)
I view working on a book in the same way a sculptor might view working on a block of wood. The first draft is generally focused on getting things in place so I can work on them. In essence, I cut out the crude features of the sculpture—but when it's done, there is still a lot of work to be done. Readers who see the book in this stage can tell what the basic arcs and characters will be, but the emotional impact is lessened by the crude edges and unfinished lines.
Here's my process in a nutshell:
Draft one: Write the book in draft form.
Draft two: Read through the entire book, fixing the major problems. Often, I'll change character personalities halfway through the first draft as I search to figure out how I want the character to sound. I don't go back then and revise, as I need to try out this personality for a while before I decide to actually use it. Similarly, often I'll drop in new characters out of the blue, pretending that they've been there all along. In the second draft, I settle on how I want things to really look, feel, and work.
Draft three: Language draft. Here I'm seeking to cut the book down by 10%. I write with a lot of extra words, knowing I'll need a trim. This will make the prose more vibrant, and will make the pacing work better.
In a perfect world, this is where I writing group the piece and/or send it to my editor. (For lack of time, my writing group is getting Draft Two of The Way of Kings. Hopefully, I'll be able to do draft three by the end of the year.)
I let readers read the book, and I take some time off of it. I begin collecting things I want to change in the book in a separate file, called "Revision notes for ***", listing the name of the book. I organize these by character and by importance and/or pervasiveness. For instance, a need to rewrite a character's motivations will be at the top. Fixing one specific scene so that it has proper foreshadowing will be near the bottom.
Once this is all done, and I've gotten feedback and had time to think, I read through the book again with my revision notes file open beside the book file itself. I actively look for places to change, kind of like a sculptor looking over the statue and seeking places to knock off jagged chunks and smooth out the sculpture’s features.
I'll do this process several times, usually. In-between, I'll often do line-edit drafts, like the language draft above, where I'm focused on getting rid of the passive voice and adding more concrete details.
