I have (so far) found the prepping has gone better than I thought it would. I had no confidence I would be able to think of enough material to fill 50,000 words. But I think I have. I also found the antagonist back story really helpful. I actually found I like him more now, even knowing all the bad things he's done. I also found the Harvard Putline really useful for working on specific parts of my story I needed to develop.
