There's a reason most every writer who's been around for a while knows about the Midling Doldrums. We get all energized at the beginning of a WIP - it's a Shiny New Idea, after all, and it's so sparkly and pretty and it's gonna be AWESOME - but once we've written 2-, 10-, 50,000 words, that excitement runs itself to the ground. You're tired. Your fingers ache, your butt's asleep in your chair, and you swear you haven't seen the outside world in months. Your characters feel flat, your plot predictable. And then, the ending is in sight. YAY! Finally, a chance to finish this up and reconnect with yourself and your family. But wait! <tires screeching> It's so much work, and what if you reach the end and discover all you've done is waste months, maybe years, on a gigantic piece of drivel?
It happens. The only people on this forum who've never felt this way are those who've yet to reach the Midling Doldrums in the first place.
Finishing a manuscript is hard. No, that's not strong enough. It's freakin' killer. It's easily one of the most difficult things I've ever done. And I'll tell you, I just finished the first draft of my third, and it doesn't get much easier. BUT! Don't forget the but! When you finally reach the end, and you type "the end" and sit back and stare at it and think "holy crap, I just FINISHED a NOVEL!" ... There is no better high in the world. (I have goose-bumps just thinking about it!) There's a euphoria that accompanies finishing that is so unlike anything else I've experienced. It's a feeling of accomplishment, pride, joy, elation...so many things. It's so worth the work, every time.
Nearly everyone thinks it'd be cool to write a book. I forget the actual statistic, but a huge majority of Americans have considered and/or want to write a book. Quite a few start one. But how many people actually FINISH writing that book? So few. It seems different since we're in the writer world, but in reality, completing a novel is a rare gift. You will never regret accomplishing that, even if it is drivel. You've written - and completed - a novel. That puts you in a higher class, those of us who gladly embrace the insanity that comes with the job description.
Hang tight, stick with it. You won't regret it.
And you aren't alone.
