A non-fiction writer pretty much has the shape of the figure in front of him or her and goes about refining it. A work of non-fiction is not as difficult to write as a work of fiction, but it's not as satisfying in the end.
Each work seems to give me the most trouble at the time I'm working on it.
I think that to a very great extent we are partners with the divine in this enterprise called history. That is an ongoing relationship, and there is absolutely no guarantee that things will automatically work out to our best advantage.
I don't work on my Sabbath. I write five-and-a-half or six days a week.
I get up around 6:30. I work from about 8:00 to 1:00, take a break for lunch, work again until about 5:00, and then go for a long walk and have dinner. Then, if my wife and I have no previous plans, we decide what to do for the evening.
There is in my work a very strong religious foreground and background. In the later work some of that tends to diminish, but it's certainly present in the early work.
