“Your time or your life!” (—Jean-Louis Servan Schreiber, in “The Art of Time.” Marlowe & Company, New York City 2000, 162 pages)

The opening line of this readable little book cuts immediately to its core message. Forget all other concepts: physical, astrophysical, cosmic, whatever. The only useful way to think of time is as the span of your life. Anything else is false dichotomy. The author delivers this in the 3-page introduction. If you read no further but grasp this idea, you’ll get your money’s worth many times over.

Servan-Schreiber had two reasons for writing the book. The first was simply to deliver the above message. That done, he describes how we can develop a healthier relationship with time than what most of us are living now. Much of the work is spent putting our current perspectives into context. But towards the end, he offers constructive and valuable guidance to a healthier and less stressful approach.

A surprisingly gratifying element of the book, presented as a backdrop, is a brief cultural history explaining how we’ve come to think of time today. We’ve gone from primitive societies that lived by daily and seasonal rhythms, to medieval villagers timing their days by church bells; from church bells to synchronized railroad time across villages, and on to the rigidly controlled hours of the mills and factories at the dawn of the industrial revolution. Finally, we come to digital watches and the modern office that parse our days into soulless pieces we pencil into schedulers. The outcome, he says, is all too familiar: stressful days, too-short vacations, frustration and anxiety, and lack of fulfillment.

Hearing all this, while disconcerting, is also validating. We all have sensed, as we’ve struggled with the competing demands of modern life, that the insanity of our days cannot be natural. But learning how we got here creates perspective. We can at least see where went off the rails. We’ve been socialized since birth to conform to unnatural temporal frameworks, and we sabotage what personal time we have with overwork, overcommitment, overconsumption and generally poor choices.

It is on this latter point that Servan-Schreiber implicitly distinguishes himself from the ubiquitous time management strategists marketing to the business crowd these days. Their works too often begin and end with setting priorities and mastering a task list. Our author instead offers a philosophy. His departure lies in the distinction between what he calls “social time” and “experienced time.” Social time — the time of calendars and clocks and meetings and social obligations — is the purview of the business books. Our author guides you past that trap and instead simply shows you your goal, the more natural realm of experienced time. In this realm, also called “perceived” time, we do not measure time so much as we feel, or sense it. We think of it less as segmented pieces and more as the measure of our days.

Experienced time is what passes when we are fully immersed in a task, or in our work in general, or in life. Clocks become our tools rather than our masters. Schedulers and task lists merely provide a framework to meet our obligations. Interestingly, all this brought to mind a passage from Catholic philosopher Bishop Fulton J. Sheen, read 40 years ago. The title I forget, but not the thought: Paraphrased, it is that the measure of one’s happiness is in how little he or she perceives the passing of time. The current work has offered an affirming convergence.

Servan-Schreiber doesn’t suggest a return to medieval rhythms. But his implicit argument is that we can achieve a productive and responsible, yet comfortable and relaxed harmony with our days. Over a few scant pages, he describes his own own history and solution. But, again departing from the business books, he leaves it to you to find your own way. He does, however, offer guideposts and an implicit warning: There are both personal and social obstacles to taking control of your time. Succeeding requires self-knowledge, self-discipline and self-interest; also motivation, will, and perseverance.

Your goal is to internalize your relationship with time to the point that you act on your days, not react to them. Think of your day as a room of fixed size, 24 hours. Will you furnish it thoughtlessly, fill it with clutter, cover the floor with debris? Or will you keep it open and breathable, with simple furniture, favorite art, a few keepsakes? This room is your life, and how you furnish it determines how comfortably you live in it.

Servan-Schreiber prefers the thoughtful room. He notes in closing that a life lived at peace with time is, in a sense, a work of art. Such a well-lived life exhibits the same elements that ancient Greeks found in art: a sense of order and equilibrium and unity, enough contrast to make it stimulating, and a cohesive harmony that imparts inner peace to the viewer.
