I made a plan to finish the book in 2021, but I had a whole month laid out for a chapter that is practically done. This morning I just started in on what was missing, which is mostly bibliographical citations. I did about half of those this morning. If I can do the same for the intro in December, then I can modify my plan enormously. I can read with both eyes, but at different distances, which makes it a bit awkward. I can see the computer with right (operated) eye, and read up close with left (as yet unoperated eye). Yet this is not seeming to slow me down.
