Deep Work: Rules for Focused Success in a Distracted World · guh.me

Types of work:
- 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.
To remain valuable in our economy, therefore, you must master the art of quickly learning complicated things.
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.
Three to four hours a day, five days a week, of uninterrupted and carefully directed concentration, it turns out, can produce a lot of valuable output.
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.
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.
To learn requires intense concentration.
To learn hard things quickly, you must focus intensely without distraction.
- This work strategy is that when you switch from some Task A to another Task B, your attention doesn’t immediately follow — a residue of your attention remains stuck thinking about the original task.
- “People experiencing attention residue after switching tasks are likely to demonstrate poor performance on that next task.”
To produce at your peak level you need to work for extended periods with full concentration on a single task free from distraction.
The Principle of Least Resistance: In a business setting, without clear feedback on the impact of various behaviors to the bottom line, we will tend toward behaviors that are easiest in the moment.
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.
Skillful management of attention is the sine qua non of the good life and the key to improving virtually every aspect of your experience.

Your work is craft, and if you hone your ability and apply it with respect and care, then like the skilled wheelwright you can generate meaning in the daily efforts of your professional life.

You have a finite amount of willpower that becomes depleted as you use it.
Philosohpies of deep work:
- Monastic philosophy of deep work scheduling. This philosophy attempts to maximize deep efforts by eliminating or radically minimizing shallow obligations.
- 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.
- Rhythmic philosophy. This philosophy argues that the easiest way to consistently start deep work sessions is to transform them into a simple regular habit.
Builiding rituals
- To make the most out of your deep work sessions, build rituals of the same level of strictness and idiosyncrasy as the important thinkers mentioned previously.
- Where you’ll work and for how long. Your ritual needs to specify a location for your deep work efforts.
- How you’ll work once you start to work. Your ritual needs rules and processes to keep your efforts structured.
- 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.
“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.
It’s important to have a public place to record and track your lead measures. This scoreboard creates a sense of competition that drives you to focus on these measures, even when other demands vie for their attention. It also provides a reinforcing source of motivation.
You should follow Kreider’s lead by injecting regular and substantial freedom from professional concerns into your day, providing you with the idleness paradoxically required to get (deep) work done.
At the end of the workday, shut down your consideration of work issues until the next morning—no after-dinner e-mail check, no mental replays of conversations, and no scheming about how you’ll handle an upcoming challenge; shut down work thinking completely.
- You must first accept the commitment that once your workday shuts down, you cannot allow even the smallest incursion of professional concerns into your field of attention.
Instead of scheduling the occasional break from distraction so you can focus, you should instead schedule the occasional break from focus to give in to distraction.
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.
“Thinking deeply” about a problem seems like a self-evident activity, but in reality it’s not. When faced with a distraction-free mental landscape, a hard problem, and time to think, the next steps can become surprisingly non-obvious. In my experience, it helps to have some structure for this deep thinking process.
I suggest starting with a careful review of the relevant variables for solving the problem and then storing these values in your working memory. Once the relevant variables are identified, define the specific next-step question you need to answer using these variables.
- Assuming you’re able to solve your next-step question, the final step of this structured approach to deep thinking is to consolidate your gains by reviewing clearly the answer you identified.
The Craftsman Approach to Tool Selection: Identify the core factors that determine success and happiness in your professional and personal life. Adopt a tool only if its positive impacts on these factors substantially outweigh its negative impacts.
