Storms of the Brain

It only occurred to me recently how apt the word brainstorm truly is. Perhaps it was prompted by watching the terrible effects of Hurricane Sandy, but I’m sure it was also related to my own story problems lately.
I’m working on my fourth Tyler Locke book right now, and I’ve been having a hell of a time wrapping my head around why the plot just wasn’t working. I had a synopsis and basic outline, but the elements weren’t gelling into a cohesive story. No matter what I did with the plot I had, it wouldn’t work. It was as if I were trying to put together a jigsaw puzzle with pieces from three different boxes. The individual elements were all great, but for some reason they didn’t fit together.
It was the dreaded writer’s block. But I’ve written five novels already, so how could that be possible? Shouldn’t I have the process figured out by now? If I were a golfer, I’d curse my case of the yips. The stuff that should be an easy putt by now was suddenly impossible. The mojo was gone, and I didn’t know if it was a permanent condition or more specific to this story.
Then my wife reminded me that this happens with every book. I always reach a point where I want to chuck the whole thing and move on to something else because I can’t figure out what’s wrong with the story. She recited my familiar lamentations back to me: “This is never going to work.” “I’ll never finish the book.” “Why did I start writing this stupid thing in the first place?”
As Christopher Vogler describes in The Writer’s Journey, I had reached the deepest chamber of the Inmost Cave to face the Ordeal. And the defining element of the Ordeal is the hero’s death and rebirth.
So I had to throw out all the assumptions I had about the story up to that point. I had to look at each and every part of it and decide whether to keep it, toss it, change it, or put it somewhere else. It was time to brainstorm.
As with the most violent storms, like hurricanes and tornadoes, everything in the story was at risk: characters, scenes, settings, action, even premise. Then I unleashed the gale. Some parts were ripped away, while others right next to them remained virtually untouched. Whole swaths of the story were decimated, while others were picked up gently and set down intact in an entirely different place.
When the storm was over, many of the individual pieces were still identifiable, but the overall rearrangement gave the story a completely new life. While real storms bring tragedy, my brainstorming was as beneficial as it was difficult. Yes, there’s a lot of cleanup still to do, but I can build something long-lasting from the wreckage.
So my question for the writers out there is, how do you get out of writer’s block? Do you unleash the brainstorm, or is there a less turbulent method to dislodge the block?
