Deep Work
Rules for focused success in a distracted world.
Newport’s claim is simple and uncomfortable: the ability to concentrate, without distraction, on something hard is getting rarer just as it becomes more valuable. This page lets you try his rules on your own attention and your own day.
Newport’s formula High-Quality Work Produced = (Time Spent) × (Intensity of Focus)
1 h 12 min = 3 h × 40%
Part 1 · The idea
Rare, just as it becomes valuable
Newport argues that two abilities decide who thrives in the new economy: mastering hard things quickly, and producing at an elite level, in both quality and speed. Both rest on deep work.
Yet most knowledge work pulls the other way. Open offices, instant messaging and an expectation of constant reply break the day into fragments, and with no clear way to measure value, people fall back on what Newport calls busyness as a proxy for productivity. The few who can still concentrate have an edge the rest are giving away.
Shallow work
Noncognitively demanding, logistical-style tasks, often performed while distracted.
It creates little new value, and almost anyone could do it.
Part 1 · Attention residue
What a quick check really costs
Sophie Leroy, a business professor, gave the cost a name: attention residue. When you switch from one task to another, part of your attention stays behind on the first, and people carrying that residue do worse on what comes next. A glance at the inbox takes a minute. The residue lasts longer.
- Checking
- 6 min
- Lost to residue
- 35 min
- Deep focus left
- 2 h 19 min
6 quick checks cost 6 min of checking and about 35 min more with attention still stuck on what you saw. Of three hours, 2 h 19 min of real focus is left.
A sketch, not a measurement: each check takes a minute and focus climbs back over the next several. Leroy’s studies show the residue exists; the minutes here are illustrative.
Rule 1 · Work deeply
Choose how deep fits your life
Willpower runs out, so Newport’s first rule is to build routines that make depth automatic. Start by choosing a depth philosophy: how deep work fits around everything else you have to do. He describes four. Answer three questions, or pick one directly.
1 How much of your work could you turn down?
2 Could you disappear for whole days at a time?
3 How practised are you at deep work?
Answer all three and the closest philosophy is picked for you.
Rhythmic
Make depth a habit: the same time every day, until starting needs no decision.
- Fits
- Most people with an ordinary job, whose days are shaped by other people.
- A week of it
- Two hours first thing every weekday, before the inbox opens.
- Example
- The chain method: mark a big X on a calendar for every day you do the deep work, and let the unbroken chain push you to keep it going.
Rule 2 · Embrace boredom
Train your attention like a muscle
Newport argues that concentration is a skill, and a mind that reaches for its phone at every idle moment loses it. You cannot switch from that to deep focus on demand. So schedule the moments you allow distraction, and keep the time between them free of it.
One of his training drills comes from memory athletes: memorise the order of a shuffled deck. Holding a sequence in your head demands the same unbroken attention as hard work, and gives you a score.
Don’t take breaks from distraction. Instead take breaks from focus.
Study the order, then turn them over.
- 7 of hearts
- Q of spades
- 3 of diamonds
- K of clubs
- 9 of clubs
- A of hearts
Cards to place, shuffled. Each one fills the next empty position.
The deal was
Rule 3 · Quit social media
Put a tool on the bench
Newport’s test for any network tool is a craftsman’s. Name the few things that matter most in your work and your life, then keep a tool only if its benefits to them substantially outweigh its harms. That a tool offers some benefit is not enough: almost everything does.
The tool
Helps 1
Hurts 2
Quit it
Social media feed: more harm than good for what matters. By the craftsman’s test, the tool goes.
Not sure? The 30-day test
Newport’s experiment for social media: quit for thirty days, without announcing it, then ask two questions.
Would the last thirty days have been notably better with it?
Did anyone care that you were gone?
Answer both after thirty days away, not before.
Rule 4 · Drain the shallows
Give every minute of the day a job
Newport does not try to abolish shallow work; he fences it in. Plan the workday in blocks before it starts, and when the day breaks the plan, redraw the blocks rather than giving up on them. Then decide how much shallow work you can afford. He suggests asking your boss for a budget, and for most people past entry level it lands between 30 and 50 percent.
To tell the two kinds apart, ask how many months it would take to train a smart new graduate to do a task. The fewer the months, the shallower the work. And set a fixed finish, such as five thirty, so the plan has to fit inside it.
Pick a brush, then click or drag across the half hours. With a keyboard, arrow keys move and Enter paints.
- Deep
- 1 h 30 min
- Shallow
- 7 h
- Breaks
- 1 h
- Shallow share
- 82%
- Longest deep stretch
- 30 min
Shallow work takes 82% of your working time, against a budget of 40%. Turn about 3 h 35 min of it into deep work, or drop it.
Your longest deep stretch is 30 min. Deep work needs long, unbroken blocks, so join them up.
When the numbers look right, run the block in the Focus Sprint Timer, or keep reading with the Focus Stack reading order.
Rule 1 · Be lazy
Shutdown complete
When the workday ends, Newport ends it completely. Downtime restores the attention deep work spends, and some insights only arrive once you stop pushing. The trouble is unfinished tasks, which keep tugging at the mind all evening.
He cites research by E. J. Masicampo and Roy Baumeister: making a concrete plan for an unfinished goal is enough to quiet the tug. So he closes every workday with the same short ritual, and ends it with a phrase.
How the book is built
One argument, four rules
Part 1 · The idea
Valuable
Deep work lets you learn hard things quickly and produce at an elite level, the two abilities the new economy rewards.
Rare
Open offices, constant connection and busyness as a proxy for productivity push most knowledge workers toward the shallow.
Meaningful
Drawing on neuroscience, psychology and philosophy, Newport argues a deep working life is also a good one: what you attend to shapes how your life feels.
Part 2 · The rules
-
Rule 1
Work deeply
- Choose a depth philosophy
- Ritualise where, how long and how you work
- Make grand gestures, like J. K. Rowling taking a hotel suite to finish a book
- Execute like a business, with the four disciplines of execution
- Be lazy: shut down at the end of the day
Try it: your philosophy · the shutdown
-
Rule 2
Embrace boredom
- Take breaks from focus, not from distraction
- Work like Teddy Roosevelt: hard deadlines for intense dashes
- Meditate productively on one problem while walking
- Memorise a deck of cards
Try it: the deck
-
Rule 3
Quit social media
- Choose tools with the craftsman approach
- Apply the law of the vital few to your internet habits
- Run the thirty-day test
- Don’t use the internet to entertain yourself
Try it: the bench
-
Rule 4
Drain the shallows
- Schedule every minute of your day
- Quantify the depth of every activity
- Ask for a shallow work budget
- Finish your work by five thirty
- Become hard to reach
Try it: the day planner
What readers underline
Reader summaries of the book’s ideas. Vote for the ones you would underline.
The ability to focus without distraction is no longer a nice-to-have; it is the central skill for producing work that cannot be copied quickly.
Busyness is often a disguise for shallow work. The scoreboard that matters is hours spent in high-intensity concentration.
Every quick check of a message leaves residue behind. The cost is not the minute you lost, but the clarity that fails to return.
A deep work ritual removes negotiation: where you work, how long you work, what you will do, and what counts as finished.
Boredom is not empty time. It is the training ground where the mind relearns how to stay with one thing.
Start this week
Pick one and put it on tomorrow’s plan.
01
Schedule one protected depth block
Pick a recurring 60–90 minute window on your calendar. Name the single deep outcome for the first block, and block email/chat/phone until it ends.
I'll do this
02
Create a shutdown ritual
Write a 3-step end-of-day ritual: review open loops, set tomorrow's first deep task, say your shutdown phrase. Practice it once this week until it sticks.
I'll do this
03
Keep a depth scoreboard
Log how many deep hours you earned today (even 0). A daily count reveals whether focus is a value or a habit.
I'll do this
04
Batch shallow work
Create two fixed windows for email, admin, and quick replies. Move every shallow task into those windows so they stop puncturing deep hours.
I'll do this
05
Protect today's depth block
Honor the scheduled deep-work block. Phone away, shallow work parked, one hard outcome in front of you.
I'll do this
06
Practice boredom on purpose
During one wait, walk, or commute today, do not check your phone. Let attention strengthen under low stimulation.
I'll do this
07
Name the deep outcome overnight
Before shutdown, write the single hard outcome for tomorrow's depth block. Starting without a target wastes the first 20 minutes.
I'll do this
08
Define your deep work philosophy
Choose monastic, bimodal, rhythmic, or journalistic. Write the calendar rule that protects it so depth is not left to mood.
I'll do this
09
Shutdown complete
Run your end-of-day ritual and say the shutdown phrase. Unfinished work stays on tomorrow's plan — not in your head.
I'll do this
The ability to perform deep work is becoming increasingly rare at exactly the same time it is becoming increasingly valuable in our economy.
