I've been preparing something--and certainly NOT a BLOG--on this precise subject.
Like many others who touch on the subject of process I always like to emphasize taking time off for reading. I don’t know why people don’t stress this more or more often.
I cannot agree more, generally, with everything you’ve said. The only exception—the one I am working on defining now—being this idea of “blogging” and the distinction with “writing.” I don’t think there is such a thing as “slogging.” That IS writing.
