Goodreads asked B.P. Gregory:

How do you deal with writer’s block?

B.P. Gregory I've never had writer's block, but I'm fermenting a pet theory that it might have to do with the characters not wanting to do what you're trying to force them into. You go to all the trouble of creating interesting, fully formed characters, so it's no surprise if they suddenly refuse the bridle of the plot.
If you can't believe your character would take certain action, the audience won't either so if you're stuck, try giving your feisty characters their head and seeing which direction they run in.
