Deep Work: Rules for Focused Success in a Distracted World

If you don’t produce, you won’t thrive—no matter how skilled or talented you are.

Clarity about what matters provides clarity about what does not.

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

what we choose to focus on and what we choose to ignore—plays in defining the quality of our life.

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.

As the author Tim Ferriss once wrote: “Develop the habit of letting small bad things happen. If you don’t, you’ll never find time for the life-changing big things.

if you keep interrupting your evening to check and respond to e-mail, or put aside a few hours after dinner to catch up on an approaching deadline, you’re robbing your directed attention centers of the uninterrupted rest they need for restoration. Even if these work dashes consume only a small amount of time, they prevent you from reaching the levels of deeper relaxation in which attention restoration can occur. Only the confidence that you’re done with work until the next day can convince your brain to downshift to the level where it can begin to recharge for the next day to follow. Put another way, trying to squeeze a little more work out of your evenings might reduce your effectiveness the next day enough that you end up getting less done than if you had instead respected a shutdown.

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.

If you can’t learn, you can’t thrive.

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.

Less mental clutter means more mental resources available for deep thinking.

Efforts to deepen your focus will struggle if you don’t simultaneously wean your mind from a dependence on distraction.

Human beings, it seems, are at their best when immersed deeply in something challenging. There

We tend to place a lot of emphasis on our circumstances, assuming that what happens to us (or fails to happen) determines how we feel. From this perspective, the small-scale details of how you spend your day aren’t that important, because what matters are the large-scale outcomes, such as whether or not you get a promotion or move to that nicer apartment. According to Gallagher, decades of research contradict this understanding. Our brains instead construct our worldview based on what we pay attention to.

In this new economy, three groups will have a particular advantage: those who can work well and creatively with intelligent machines, those who are the best at what they do, and those with access to capital.

If you service low-impact activities, therefore, you're taking away time you could be spending on higher-impact activities. It's a zero-sum game.

[Great creative minds] think like artists but work like accountants.

Once your brain has become accustomed to on-demand distraction, Nass discovered, it’s hard to shake the addiction even when you want to concentrate. To put this more concretely: If every moment of potential boredom in your life—say, having to wait five minutes in line or sit alone in a restaurant until a friend arrives—is relieved with a quick glance at your smartphone, then your brain has likely been rewired to a point where, like the “mental wrecks” in Nass’s research, it’s not ready for deep work—even if you regularly schedule time to practice this concentration.

Another key commitment for succeeding with this strategy is to support your commitment to shutting down with a strict shutdown ritual that you use at the end of the workday to maximize the probability that you succeed. In more detail, this ritual should ensure that every incomplete task, goal, or project has been reviewed and that for each you have confirmed that either (1) you have a plan you trust for its completion, or (2) it’s captured in a place where it will be revisited when the time is right. The process should be an algorithm: a series of steps you always conduct, one after another. When you’re done, have a set phrase you say that indicates completion (to end my own ritual, I say, “Shutdown complete”). This final step sounds cheesy, but it provides a simple cue to your mind that it’s safe to release work-related thoughts for the rest of the day.

(As Nietzsche said: “It is only ideas gained from walking that have any worth.”)

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.

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.

The task of a craftsman, they conclude, “is not to generate meaning, but rather to cultivate in himself the skill of discerning the meanings that are already there.

To produce at your peak level you need to work for extended periods with full concentration on a single task free from distraction. Put another way, the type of work that optimizes your performance is deep work.

Ericsson notes that for a novice, somewhere around an hour a day of intense concentration seems to be a limit, while for experts this number can expand to as many as four hours—but rarely more.

To remain valuable in our economy, therefore, you must master the art of quickly learning complicated things. This task requires deep work. If you don’t cultivate this ability, you’re likely to fall behind as technology advances. The

Your goal is not to stick to a given schedule at all costs; it’s instead to maintain, at all times, a thoughtful say in what you’re doing with your time going forward—even

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.

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.” For

A side effect of memory training, in other words, is an improvement in your general ability to concentrate. This ability can then be fruitfully applied to any task demanding deep work.
