Chip at this a little at a time, I guess. Even if it's a good idea to take intrinsic motivation and make it extrinsic, there's gotta be a better way than a writing blog, for one who is not a pantser. Maybe a blog that says, hey guys I wrote something, but I'm not telling you what? For pantsers, it's as perfect a format as any: Andy Weir wrote The Martian as a series of blog posts, which was collected into an e-book, became a best-seller, bought by Houghton-Mifflin to distribute, became a best-seller, turned into a Ridley Scott film, became a blockbuster.
Because Andy Weir is a pantser. He loved getting Watney into trouble he didn't think anyone would have been able to get out of, and then, with the trouble already established and his readers awaiting the consummation of the cliffhanger, he was forced to come up with something awesome and clever for Watney to do to get out of it. The perfect format for this kind of thing: nobody really ever doubts Watney's ability to survive, but read on to discover how.
