Still on sabbatical. Thirty days. Work rhythms have been more predictable and disciplined lately. Up early enough, write until noon or so. Out of this, a chapter takes shape–the third chapter. I just sent it off to the editor. Just over 10,000 words. Fourty-eight references. Ten original figures plus the linked-clickable animated index. Something like 44 pages. Embedded notes about “could do more this this” and “could do more with that.” Threaded through is a realization that I’ve been working on this chapter for a few years. And then up next will be a hard revision of the second chapter, hacking away at its extralong bulk, then adding back another 3,500 words. It’s basically a concept review: three concepts. And two are done; one remains.
