Deep Work: Rules for Focused Success in a Distracted World

by Cal Newport

Deep Work: Professional activities performed in a state of distraction-free concentration that push your cognitive capabilities to their limit. These efforts create new value, improve your skill, and are hard to replicate.

Shallow Work: Noncognitively demanding, logistical-style tasks, often performed while distracted. These efforts tend to not create much new value in the world and are easy to replicate.

The Deep Work Hypothesis: The ability to perform deep work is becoming increasingly rare at exactly the same time it is becoming increasingly valuable in our economy. As a consequence, the few who cultivate this skill, and then make it the core of their working life, will thrive.

Two Core Abilities for Thriving in the New Economy 1. The ability to quickly master hard things. 2. The ability to produce at an elite level, in terms of both quality and speed.

Silver alone who put in the effort to adapt these skills to the new and more lucrative territory of election forecasting. This provides another general observation for joining the ranks of winners in our economy: If you don’t produce, you won’t thrive—no matter how skilled or talented you are.

The two core abilities just described depend on your ability to perform deep work. If you haven’t mastered this foundational skill, you’ll struggle to learn hard things or produce at an elite level.

Throughout The Intellectual Life, Sertillanges recognizes the necessity of mastering complicated material and helps prepare the reader for this challenge.

Busyness as Proxy for Productivity: In the absence of clear indicators of what it means to be productive and valuable in their jobs, many knowledge workers turn back toward an industrial indicator of productivity: doing lots of stuff in a visible manner.

Like fingers pointing to the moon, other diverse disciplines from anthropology to education, behavioral economics to family counseling, similarly suggest that the skillful management of attention is the sine qua non of the good life and the key to improving virtually every aspect of your experience.

If you focus on a cancer diagnosis, you and your life become unhappy and dark, but if you focus instead on an evening martini, you and your life become more pleasant—even though the circumstances in both scenarios are the same. As Gallagher summarizes: “Who you are, what you think, feel, and do, what you love—is the sum of what you focus on.”

“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).

Throughout most of human history, to be a blacksmith or a wheelwright wasn’t glamorous. But this doesn’t matter, as the specifics of the work are irrelevant. The meaning uncovered by such efforts is due to the skill and appreciation inherent in craftsmanship—not the outcomes of their work. Put another way, a wooden wheel is not noble, but its shaping can be. The same applies to knowledge work. You don’t need a rarified job; you need instead a rarified approach to your work.

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.” This is perhaps the best way to sum up the argument of this chapter and of Part 1 more broadly: A deep life is a good life, any way you look at it.

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

Give and Take, promotes the practice of giving of your time and attention, without expectation of something in return, as a key strategy in professional advancement.

The ability to concentrate intensely is a skill that must be trained.

Efforts to deepen your focus will struggle if you don’t simultaneously wean your mind from a dependence on distraction. Much in the same way that athletes must take care of their bodies outside of their training sessions, you’ll struggle to achieve the deepest levels of concentration if you spend the rest of your time fleeing the slightest hint of boredom.

So we have scales that allow us to divide up people into people who multitask all the time and people who rarely do, and the differences are remarkable. People who multitask all the time can’t filter out irrelevancy. They can’t manage a working memory. They’re chronically distracted. They initiate much larger parts of their brain that are irrelevant to the task at hand… they’re pretty much mental wrecks.

Don’t Take Breaks from Distraction. Instead Take Breaks from Focus.

The idea motivating this strategy is that the use of a distracting service does not, by itself, reduce your brain’s ability to focus. It’s instead the constant switching from low-stimuli/high-value activities to high-stimuli/low-value activities, at the slightest hint of boredom or cognitive challenge, that teaches your mind to never tolerate an absence of novelty. This constant switching can be understood analogously as weakening the mental muscles responsible for organizing the many sources vying for your attention. By segregating Internet use (and therefore segregating distractions) you’re minimizing the number of times you give in to distraction, and by doing so you let these attention-selecting muscles strengthen.

One place where this strategy becomes particularly difficult outside work is when you’re forced to wait (for example, standing in line at a store). It’s crucial in these situations that if you’re in an offline block, you simply gird yourself for the temporary boredom, and fight through it with only the company of your thoughts. To simply wait and be bored has become a novel experience in modern life, but from the perspective of concentration training, it’s incredibly valuable.

To summarize, to succeed with deep work you must rewire your brain to be comfortable resisting distracting stimuli. This doesn’t mean that you have to eliminate distracting behaviors; it’s sufficient that you instead eliminate the ability of such behaviors to hijack your attention. The simple strategy proposed here of scheduling Internet blocks goes a long way toward helping you regain this attention autonomy.

The goal of productive meditation is to take a period in which you’re occupied physically but not mentally—walking, jogging, driving, showering—and focus your attention on a single well-defined professional problem. Depending on your profession, this problem might be outlining an article, writing a talk, making progress on a proof, or attempting to sharpen a business strategy. As in mindfulness meditation, you must continue to bring your attention back to the problem at hand when it wanders or stalls.

Suggestion #1: Be Wary of Distractions and Looping

Suggestion #2: Structure Your Deep Thinking

Once the relevant variables are identified, define the specific next-step question you need to answer using these variables. In the book chapter example, this next-step question might be, “How am I going to effectively open this chapter?,” and for a proof it might be, “What can go wrong if I don’t assume this property holds?” With the relevant variables stored and the next-step question identified, you now have a specific target for your attention.

What’s the alternative to this state of affairs? Bennett suggests that his typical man see his sixteen free hours as a “day within a day,” explaining, “during those sixteen hours he is free; he is not a wage-earner; he is not preoccupied with monetary cares; he is just as good as a man with a private income.” Accordingly, the typical man should instead use this time as an aristocrat would: to perform rigorous self-improvement—a task that, according to Bennett, involves, primarily, reading great literature and poetry.

You might expect that in the intervening decades, a period in which this middle class exploded in size worldwide, our thinking about leisure time would have evolved. But it has not. If anything, with the rise of the Internet and the low-brow attention economy it supports, the average forty-hour-a-week employee—especially those in my tech-savvy Millennial generation—has seen the quality of his or her leisure time remain degraded, consisting primarily of a blur of distracted clicks on least-common-denominator digital entertainment.

These sites are especially harmful after the workday is over, where the freedom in your schedule enables them to become central to your leisure time. If you’re waiting in line, or waiting for the plot to pick up in a TV show, or waiting to finish eating a meal, they provide a cognitive crutch to ensure you eliminate any chance of boredom. As I argued in Rule #2, however, such behavior is dangerous, as it weakens your mind’s general ability to resist distraction, making deep work difficult later when you really want to concentrate.

Put more thought into your leisure time. In other words, this strategy suggests that when it comes to your relaxation, don’t default to whatever catches your attention at the moment, but instead dedicate some advance thinking to the question of how you want to spend your “day within a day.” Addictive websites of the type mentioned previously thrive in a vacuum: If you haven’t given yourself something to do in a given moment, they’ll always beckon as an appealing option. If you instead fill this free time with something of more quality, their grip on your attention will loosen. It’s crucial, therefore, that you figure out in advance what you’re going to do with your evenings and weekends before they begin. Structured hobbies provide good fodder for these hours, as they generate specific actions with specific goals to fill your time. A set program of reading, à la Bennett, where you spend regular time each night making progress on a series of deliberately chosen books, is also a good option, as is, of course, exercise or the enjoyment of good (in-person) company.

One of the chief things which my typical man has to learn is that the mental faculties are capable of a continuous hard activity; they do not tire like an arm or a leg. All they want is change—not rest, except in sleep.

To summarize, if you want to eliminate the addictive pull of entertainment sites on your time and attention, give your brain a quality alternative. Not only will this preserve your ability to resist distraction and concentrate, but you might even fulfill Arnold Bennett’s ambitious goal of experiencing, perhaps for the first time, what it means to live, and not just exist.

A commitment to deep work is not a moral stance and it’s not a philosophical statement—it is instead a pragmatic recognition that the ability to concentrate is a skill that gets valuable things done. Deep work is important, in other words, not because distraction is evil, but because it enabled Bill Gates to start a billion-dollar industry in less than a semester.

But if you’re willing to sidestep these comforts and fears, and instead struggle to deploy your mind to its fullest capacity to create things that matter, then you’ll discover, as others have before you, that depth generates a life rich with productivity and meaning. In Part 1, I quoted writer Winifred Gallagher saying, “I’ll live the focused life, because it’s the best kind there is.” I agree.
