Write the book the way I'd want it to be if I were reading it.
I mean, yes, I write the sort of books I like to read. I often write books that I wish there were more of for me to read. But that's more of a general sense-of-the-thing approach. I've never actually sat down as I was outlining and asked myself, "If I were reading this story, how would I want it to begin?" "If I were reading this story, what would I want to happen after this event?" and so on.
I don't know if this is actually going to work. Mostly because my favorite bits of stories (as a reader) are often the bits it didn't even occur to me might happen. But I'm interested to see how it'll go. :D
Have you had any new and interesting brainstorms about the writing process lately?
