I’ll say this for doing NaNoWriMo–even unofficially: it’s helped me build momentum in WAR OF MAGIC.
Especially through some tricky parts. I’d never written a naval battle–well, a battle between attacking ships and a moderately fortified city, anyway. I’m sure that my competitive spirit and trying to keep up with something remotely like the NaNo pace helped me get through that faster.
Not that I’m remotely close to the pace necessary to complete 50,000 words in a month–yet. But I am definitely building momentum in spite of a few real life issues that might have derailed me otherwise.
I’ve also got a pretty good plan–as much as a discovery writer plans ahead, anyway–for the next ten or so chapters. That should help.
