This time it's happening when I have only a chapter and a half to go on INSURGENTS. Possibly because this book is shorter than my usual, the internal demons were goofing off and thinking, "Oh, we don't need to attack until she reaches 75,000 words." Unfortunately, it seems that somebody blew the alarm whistle: "She's not going to get to 75,000 words on this book! Fire when ready!"
So here we are again, and the only way forward is through the Insecurity Demons. Arguing with them does no good; I simply have to get my head down and adopt the attitude that I don't care what they say about quality, I'm going to finish this thing. Today I've done 1600 words in that mode. It's not fun. But sometimes it's necessary.
The demons usually STFU after it becomes clear that they're not able to stop me writing. But this time I'm so close to the end that they may be able to keep it up for the rest of the book.
Full speed ahead. And damn the torpedos.
