Actually, quite well. The question is, though, how do I figure out how much is still to be done? Today I reached 30,000 words, i.e., 50% of my original estimate of 60,000 words.
However, I am certainly more than halfway through the story. Counting scenes in the script, I am up to scene 86 of 116. That’s 74%. That seems more like it! I think I had better count it that way in future. So, I am almost three-quarters of the way through the first draft. Excellent!
