^This was some kind of business theory which got applied to education in the not too distant past....the whole outcomes-based-learning kind of thing. The gist being that if you decided where you wanted to go, or what you wanted to learn, you could then figure out how to get there (or something far more filled with important jargon-y words, but you get the idea.)
How does this apply to writing (she asked rhetorically)....well, glad you asked.
First off, let me tell you two things about my process:
1. I never outline.
2. I always have some idea what the finished product might be like before I begin. (It is not always accurate, but it is a vision of sorts, which helps me navigate through the writing.)
So, I thought I'd try a little something....because I'm wild like that.
Usually, when I start a book, I open a "fake" document about the book that I call "the manifesto" in which I write all things pertaining to said book that I am not ready to put in the book yet. Or it might be just me dreaming about the characters and such in the fake document. So I thought I'd try a little trick....what if I wrote the query BEFORE I wrote the book (in the manifesto, of course). I mean, if I have a title, an idea and a voice for the writing, who needs all the details?
So, I wrote some queries for some books before I wrote them and you know what? That little paragraph of description really helped me figure out a lot about my book. It made me think, "Dang! I want to write that book!"
So, if you're stuck, try writing the query. It's a lot more fun to write a query when you don't have to than when you do.
