For all who struggle with waiting to hear back from editors and/or agents -- I feel your pain! I still haven't found out whether my last novel will need revisions, because the folks who make such decisions have been out of town. Meanwhile, I've nearly finished another novel -- something done completely for fun, for a younger audience than what I'm used to.
Before I can write the final scene, though, I have to do some research regarding my setting. It's a place I visited years ago, but I'm having trouble remembering exactly what it looks like, so this morning I hauled out my old photo albums and am trying to jog my memory. But this too is testing my patience, not just because my memories are coming slowly but because I'm eager to write and can't (yet). At one point I was tempted to change the location -- but this decision would have been based solely on impatience, because the setting goes perfectly with what I want to achieve in that final scene. So once again I just have to be patient. Arrrgh!
(Nobody said writing was easy!)
