Have you ever heard your characters ask that before?
"LET ME OUT OF THE BOX!"
Guess its more of a demand than a question...
Seriously though, sometimes we put our characters into such stilted, boring, formal conflict that we forget to let them breathe. Let them tell us where to go and what to write. We get so busy complaining about our characters not doing what we want them to, not flowing easily into the plot we stuffed them into, that we don't consider the fact they might be trying to tell us they have a better way.
Can't help but see the spiritual analogy in that (in reverse). We try to force our own plans and our will, always forgetting that God's will and plans are so much better, higher, and greater than our own. Maybe it's time to stop forcing it and let God move us.
And in your writing, if your plot is stuck, maybe it's time to try a different route. Think outside the box. If Plan A is obvious and the best answer logically, think about what Plan B would look like and give it a whirl. You might find an amazing twist that is just what your story needs. Don't be afraid to keep asking what if.
Remember, plans are just plans. Not guarantees.
For us, and for our characters ;)
