But as those chunks [of time] get separated and fragmented, my productivity as a novelist drops spectacularly. What replaces it? Instead of a novel that will be around for a long time, and that will, with luck, be read by many people, there is a bunch of e-mail messages that I have sent out to individual persons, and a few speeches given at various conferences.
That is not such a terrible outcome, but neither is it an especially good outcome. The quality of my e-mails and public speaking is, in my view, nowhere near that of my novels. So for me it comes down to the following choice: I can distribute material of bad-to-mediocre quality to a small number of people, or I can distribute material of higher quality to more people. But I can’t do both; the first one obliterates the second.
