I've set myself a words-per-day target (2000) and have already blown by it for the few days I've been immersed. The speed of my typing (and the relative completeness of the story in my head) could mean a decent first draft well before the end of the year. Sara is coming by for dinner tonight; since she already has a book under belt and another on the way, we can have a good discussion about my early progress (and initial shortcomings...I am going to need a thick skin for this process, I think).
Once I get two chapters in good enough shape, I will complete the proposal and send it off to the publisher - then see what happens next. Sara will be an important adviser to me in the quality check for the proposal. As I said, it is all a bit of a mystery to me, but each day, the more I write, the more enjoyable it becomes. It is also an appropriate activity to mark the Dwarf Tomato Project milestone of having our first nine new varieties in seed catalogs this year.
And so finally - after thinking/talking about it for years, after the subtle (and not so subtle) hints and comments and encouragements from Sue (rapidly increasing each year), it is time, and it is in progress. And it feels pretty good!
