Deep Work: Rules for Focused Success in a Distracted World

by Cal Newport

Who you are, what you think, feel, and do, what you love—is the sum of what you focus on.”

After a bad or disrupting occurrence in your life, Fredrickson’s research shows, what you choose to focus on exerts significant leverage on your attitude going forward.

These elderly subjects were not happier because their life circumstances were better than those of the young subjects; they were instead happier because they had rewired their brains to ignore the negative and savor the positive. By skillfully managing their attention, they improved their world without changing anything concrete about it.

Gallagher’s theory, therefore, predicts that if you spend enough time in this state, your mind will understand your world as rich in meaning and importance.

‘the idle mind is the devil’s workshop’ … when you lose focus, your mind tends to fix on what could be wrong with your life instead of what’s right.”

A workday driven by the shallow, from a neurological perspective, is likely to be a draining and upsetting day, even if most of the shallow things that capture your attention seem harmless or fun.

In work (and especially knowledge work), to increase the time you spend in a state of depth is to leverage the complex machinery of the human brain in a way that for several different neurological reasons maximizes the meaning and satisfaction you’ll associate with your working life.

The best moments usually occur when a person’s body or mind is stretched to its limits in a voluntary effort to accomplish something difficult and worthwhile.” Csikszentmihalyi calls this mental state flow (a term he popularized with a 1990 book of the same title).

Ironically, jobs are actually easier to enjoy than free time, because like flow activities they have built-in goals, feedback rules, and challenges, all of which encourage one to become involved in one’s work, to concentrate and lose oneself in it. Free time, on the other hand, is unstructured, and requires much greater effort to be shaped into something that can be enjoyed.

as the ESM studies confirmed, the more such flow experiences that occur in a given week, the higher the subject’s life satisfaction. Human beings, it seems, are at their best when immersed deeply in something challenging.

the feeling of going deep is in itself very rewarding. Our minds like this challenge, regardless of the subject.

Csikszentmihalyi then explains that it’s even more important that the individual learn how to seek out opportunities for flow. This, ultimately, is the lesson to come away with from our brief foray into the world of experimental psychology: To build your working life around the experience of flow produced by deep work is a proven path to deep satisfaction.

Consider this quote from the coding prodigy Santiago Gonzalez describing his work to an interviewer: Beautiful code is short and concise, so if you were to give that code to another programmer they would say, “oh, that’s well written code.” It’s much like as if you were writing a poem.

The Pragmatic Programmer, a well-regarded book in the computer programming field, makes this connection between code and old-style craftsmanship more directly by quoting the medieval quarry worker’s creed in its preface: “We who cut mere stones must always be envisioning cathedrals.” The book then elaborates that computer programmers must see their work in the same way:

Within the overall structure of a project there is always room for individuality and craftsmanship … One hundred years from now, our engineering may seem as archaic as the techniques used by medieval cathedral builders seem to today’s civil engineers, while our craftsmanship will still be honored.

It’s as if our species has evolved into one that flourishes in depth and wallows in shallowness,

I earlier quoted Winifred Gallagher, the converted disciple of depth, saying, “I’ll live the focused life, because it’s the best kind there is.”

A deep life is a good life, any way you look at it.

He imagines a process in which you spend ninety minutes inside, take a ninety-minute break, and repeat two or three times—at which point your brain will have achieved its limit of concentration for the day.

Unfortunately, this vision is far from our current reality. We instead find ourselves in distracting open offices where inboxes cannot be neglected and meetings are incessant—a setting where colleagues would rather you respond quickly to their latest e-mail than produce the best possible results.

You have a finite amount of willpower that becomes depleted as you use it.

Your will, in other words, is not a manifestation of your character that you can deploy without limit; it’s instead like a muscle that tires. This is why the subjects in the Hofmann and Baumeister study had such a hard time fighting desires—over time these distractions drained their finite pool of willpower until they could no longer resist. The same will happen to you, regardless of your intentions—unless, that is, you’re smart about your habits.

The key to developing a deep work habit is to move beyond good intentions and add routines and rituals to your working life designed to minimize the amount of your limited willpower necessary to transition into and maintain a state of unbroken concentration.

attempting to schedule deep work in an ad hoc fashion is not an effective way to manage your limited willpower.) But this example highlights a general warning

Practitioners of the monastic philosophy tend to have a well-defined and highly valued professional goal that they’re pursuing, and the bulk of their professional success comes from doing this one thing exceptionally well.

The productivity equation is a non-linear one, in other words. This accounts for why I am a bad correspondent and why I very rarely accept speaking engagements. If I organize my life in such a way that I get lots of long, consecutive, uninterrupted time-chunks, I can write novels. But as those chunks get separated and fragmented, my productivity as a novelist drops spectacularly.

On the other hand, if you’re inside this pool—someone whose contribution to the world is discrete, clear, and individualized*—then you should give this philosophy serious consideration, as it might be the deciding factor between an average career and one that will be remembered.

He would then meditate and walk in the woods to clarify his thinking in preparation for the next day’s writing.

Jung’s approach is what I call the bimodal philosophy of deep work. This philosophy asks that you divide your time, dedicating some clearly defined stretches to deep pursuits and leaving the rest open to everything else. During the deep time, the bimodal worker will act monastically—seeking intense and uninterrupted concentration. During the shallow time, such focus is not prioritized. This division of time between deep and open can happen on multiple scales. For example, on the scale of a week, you might dedicate a four-day weekend to depth and the rest to open time. Similarly, on the scale of a year, you might dedicate one season to contain most of your deep stretches (as many academics do over the summer or while on sabbatical).

As Jung, Grant, and Perlow’s subjects discovered, people will usually respect your right to become inaccessible if these periods are well defined and well advertised, and outside these stretches, you’re once again easy to find.

the rhythmic philosophy. This philosophy argues that the easiest way to consistently start deep work sessions is to transform them into a simple regular habit. The goal, in other words, is to generate a rhythm for this work that removes the need for you to invest energy in deciding if and when you’re going to go deep.

he decided he would try to schedule these chunks in an ad hoc manner whenever appropriate openings in his schedule arose. Not surprisingly, this strategy didn’t yield much productivity. In a dissertation boot camp Chappell had attended the year before, he’d managed to produce a full thesis chapter in a single week of rigorous deep work. After he accepted his full-time job, he managed to produce only a single additional chapter in the entire first year he was working.

By supporting deep work with rock-solid routines that make sure a little bit gets done on a regular basis, the rhythmic scheduler will often log a larger total number of deep hours per year.

Isaacson was methodic: Any time he could find some free time, he would switch into a deep work mode and hammer away at his book. This is how, it turns out, one can write a nine-hundred-page book on the side while spending the bulk of one’s day becoming one of the country’s best magazine writers.

the journalistic philosophy of deep work scheduling remains difficult to pull off. But if you’re confident in the value of what you’re trying to produce, and practiced in the skill of going deep (a skill we will continue to develop in the strategies that follow), it can be a surprisingly robust way to squeeze out large amounts of depth from an otherwise demanding schedule.

There is a popular notion that artists work from inspiration—that there is some strike or bolt or bubbling up of creative mojo from who knows where … but I hope [my work] makes clear that waiting for inspiration to strike is a terrible, terrible plan. In fact, perhaps the single best piece of advice I can offer to anyone trying to do creative work is to ignore inspiration.

In a New York Times column on the topic, David Brooks summarizes this reality more bluntly: “[Great creative minds] think like artists but work like accountants.”

Where you’ll work and for how long. Your ritual needs to specify a location for your deep work efforts. This location can be as simple as your normal office with the door shut and desk cleaned off (a colleague of mine likes to put a hotel-style “do not disturb” sign on his office door when he’s tackling something difficult). If it’s possible to identify a location used only for depth—for instance, a conference room or quiet library—the positive effect can be even greater. (If you work in an open office plan, this need to find a deep work retreat becomes particularly important.) Regardless of where you work, be sure to also give yourself a specific time frame to keep the session a discrete challenge and not an open-ended slog.

• How you’ll work once you start to work. Your ritual needs rules and processes to keep your efforts structured. For example, you might institute a ban on any Internet use, or maintain a metric such as words produced per twenty-minute interval to keep your concentration honed. Without this structure, you’ll have to mentally litigate again and again what you should and should not be doing during these sessions and keep trying to assess whether you’re working sufficiently hard. These are unnecessary drains on your willpower reserves.

• How you’ll support your work. Your ritual needs to ensure your brain gets the support it needs to keep operating at a high level of depth. For example, the ritual might specify that you start with a cup of good coffee, or make sure you have access to enough food of the right type to maintain energy, or integrate light exercise such as walking to help keep the mind clear. (As Nietzsche said: “It is only ideas gained from walking that have any worth.”) This support might also include environmental factors, such as organizing the raw materials of your work to minimize energy-dissipating friction (as we saw with Caro’s example). To maximize your success, you need...

Rowling’s decision to check into a luxurious hotel suite near Edinburgh Castle is an example of a curious but effective strategy in the world of deep work: the grand gesture. The concept is simple: By leveraging a radical change to your normal environment, coupled perhaps with a significant investment of effort or money, all dedicated toward supporting a deep work task, you increase the perceived importance of the task. This boost in importance reduces your mind’s instinct to procrastinate and delivers an injection of motivation and energy.

In all of these examples, it’s not just the change of environment or seeking of quiet that enables more depth. The dominant force is the psychology of committing so seriously to the task at hand. To put yourself in an exotic location to focus on a writing project, or to take a week off from work just to think, or to lock yourself in a hotel room until you complete an important invention: These gestures push your deep goal to a level of mental priority that helps unlock the needed mental resources. Sometimes to go deep, you must first go big.

For some types of problems, working with someone else at the proverbial shared whiteboard can push you deeper than if you were working alone. The presence of the other party waiting for your next insight—be it someone physically in the same room or collaborating with you virtually—can short-circuit the natural instinct to avoid depth.

distraction remains a destroyer of depth. Therefore, the hub-and-spoke model provides a crucial template. Separate your pursuit of serendipitous encounters from your efforts to think deeply and build on these inspirations. You should try to optimize each effort separately, as opposed to mixing them together into a sludge that impedes both goals.

even when you retreat to a spoke to think deeply, when it’s reasonable to leverage the whiteboard effect, do so. By working side by side with someone on a problem, you can push each other toward deeper levels of depth, and therefore toward the generation of more and more valuable output as compared to working alone.

As the authors of The 4 Disciplines of Execution explain, “The more you try to do, the less you actually accomplish.” They elaborate that execution should be aimed at a small number of “wildly important goals.” This simplicity will help focus an organization’s energy to a sufficient intensity to ignite real results.

For an individual focused on deep work, the implication is that you should identify a small number of ambitious outcomes to pursue with your deep work hours. The general exhortation to “spend more time working deeply” doesn’t spark a lot of enthusiasm. To instead have a specific goal that would return tangible and substantial professional benefits will generate a steadier stream of enthusiasm.

If you want to win the war for attention, don’t try to say ‘no’ to the trivial distractions you find on the information smorgasbord; try to say ‘yes’ to the subject that arouses a terrifying longing, and let the terrifying longing crowd out everything else.”

lead measures turn your attention to improving the behaviors you directly control in the near future that will then have a positive impact on your long-term goals.

Discipline #3: Keep a Compelling Scoreboard “People play differently when they’re keeping score,” the 4DX authors explain. They then elaborate that when attempting to drive your team’s engagement toward your organization’s wildly important goal, it’s important that they have a public place to record and track their lead measures.
