I managed. I read the whole paper, without hyperlinks. I tried to let myself do nothing, which led to a long, MP3-free walk, a nap and some more reading, an actual novel. I drank herb tea (caffeine was not helpful) and stared out the window. I tried to allow myself to be less purposeful, not to care what was piling up in my personal cyberspace, and not to think about how busy I was going to be the next morning. I cooked, then went to bed, and read some more.

GRADUALLY, over this and the next couple of weekends  one of which stretched from Friday night until Monday morning, like the old days  I adapted.

But recidivism quickly followed; there were important things to do  deadlines, urgent communications. You know how it is. I called Andrea Bauer, an executive and career development coach in San Carlos, Calif. She assured me that, oddly enough, it takes work to stop working. “It takes different formats for different people, and you have to build up to it; you can’t run five miles if you’ve never run at all.” Increasingly, I realized that there is more to the secular Sabbath than an impulse, or even a day off from e-mail. And there are reasons that nonsecular Sabbaths  the holy days of Christians, Jews and Muslims  have rules that require discipline. Even for the nonreligious, those rules were once imposed: You need not be elderly to remember when we had no choice but to reduce activity on Sundays; stores and offices  even restaurants  were closed, there were certainly no electronics, and we were largely occupied by ourselves or our families.

Now it’s up to us, and, as Dr. Levy says, there’s little encouragement. “One of the problems with needing to slow down is that within the climate of our primary culture it sounds wishy-washy,” he said.

But what’s wishy-washy about taking time off? It didn’t seem to me that I had to collect Social Security before I realized that a 70-hour week was nearly as productive as an 80-hour one, and if I couldn’t get it all done in either, it certainly wasn’t because I was taking too much time off.
