I am having this battle with myself with WIP2, because as I reread through to edit/revise I begin to second guess the level of detail I've put in. Why did XYZ character need a detailed account of her walk to ABC location? What if I simply put "She made it there in record time blah blah blah"? This would work too, and propel my plot arc further along perhaps...or would I be losing a chance to show off a facet of her character?
The level of detail vs. moving the story along is a interesting strategizing moment. I tend to over-detail things at first, but like when revisiting what I'd written, I realize that sometimes getting to the point is time better spent.
