New beginnings in unexpected places

Here we are in week three of NaNoWriMo.  And what a wild ride it has been.  I thought a couple of times that I might be sort of cheating this year since I've *technically* been working on the same novel I originally started with back in 2008.  But I used the following rational to counter that:

1. I had scrapped every piece of shitty writing I'd done to date and had no plans to even look back at any of it for reference.  (yes, it was that shitty!)
   
2. I had plotted out a structure for the entire story complete with several subplots all neatly tied in with each other
3. I had even changed the main character's name since we named Baby Sister the original character name when she was born

With the new plot and new character motivations I knew the book would be far different than I had envisioned when I first came up with the idea.  But guess what?  I never needed to rationalize a single little thing!

I had a rough start after I got through the prologue (which hasn't really changed much over each iteration of attempts).  I wrote myself into a corner where I knew my character would never be stupid enough to do what I was trying to make her do as a means to get her physically from one place to another.  I wasted days of writing more crap dragging one scene out and never getting anywhere but behind in my target word count. I was honestly getting worried.  What if I hadn't prepared enough?  What if I couldn't figure out how to translate a plot to a real story?  What if I failed?

Then I went for a run.

And I had the best run of my life - five miles in a hour which is insanely fast for me!

I must have shook up my brain with all that pounding of treadmill because I came off that run with a shit-eating grin glued to my face AND a way to get myself out of the corner and fix everything!

I rushed home and wrote like a mad woman.  I was able to salvage most of that original crappy chapter and after adding seven hundred or so words I was back on track toward where I needed to be heading.  I was even on my way to the next mile-marker plot point.

And I know I was still high from that amazing run when the next morning in the shower I had the one piece of unknown I'd been trying to solve SINCE THE BEGINNING IN 2008 just fall into place.  It was so earth-shattering when it happened I expected to feel the earth move beneath me.  But it didn't.  One minute I had this question of "how does that happen that will make sense and be believable" playing over and over in my subconscious.  And the next it was clear as day how it would all work.  The last loose end was no longer loose!  Plus, it was so fundamental that it changed everything.  Including the title which had been the one constant from the beginning.

I wonder if anyone else who embarked on this journey is experiencing anything similar.  Because it is crazy how unbelievable it all is and I'm only half done!
