I have a theory: writer's block happens when the writer doesn't know what happens next. The solution I have for writer's block has worked very well for me.

The chapter I wrote today necessarily started out boring. I hadn't included a certain main character in AM book 3 yet, and he needed to make an appearance. But I didn't really know what to write other than boring stuff. So I threw in a wrench, I added conflict, and now I have a major piece of support for my plot line.

If you have writer's block, or otherwise aren't sure what to write, then add conflict!

I have a new story idea, but I wasn't sure what to write, as I just wanted to capture enough of the idea that I wouldn't forget it.

So, even then, I added conflict. Check this for the first line of a story. Easy to write a scene when you start with conflict.

"I am seventeen years old, and I'm about to kill the President."

It works pretty well for my editor, too. His template for the post-apocalyptic genre includes checking for action. His analysis? "No problem here. Whoa!"
