This is it: My words are not sacred. (Scared, maybe sometimes, but not sacred.)
I thought they were so great when I wrote them...and then edited them to death...and then a little more just for good measure. Now I am back at them after a 2-month sabbatical and I find that they can become even better.
They can be changed.
This is why they should be scared.
After arriving at the end of my story, I know the beginning so much better and it's very exciting to see it coming together, fitting like puzzle pieces from one chapter to the next to the next to the next.
Loving this part of the process.
