Scale-Smart Productivity

The Mindworker

Dennis Nehrenheim M.Sc. — Tue, 09 Jun 2026 07:46:26 GMT

Many men die at twenty-five and aren’t buried until they’re seventy-five.

This line aged rather well. It points to something many people experience, but rarely talk about. A person can remain physically alive for decades while slowly losing touch with themselves — their attention, emotions, values, or sense of meaning. In the physical world, neglect is usually visible. If someone stops caring for their body, eventually the consequences appear on the surface. Inner neglect works differently. A person can continue functioning outwardly while becoming increasingly disconnected underneath it all. They still answer emails, attend meetings, raise children, pay bills, and make plans for the future. Yet under it all, no one is home.

A century ago, most workers exhausted their bodies. Today, many people experience something harder to describe. They sit in climate-controlled rooms, barely moving, spending entire days navigating abstractions, emotional currents, competing demands, and endless streams of information. They answer messages, absorb information, manage reactions, and continuously negotiate what deserves their attention. By evening, they feel depleted in a way the language of the industrial age struggles to explain, because outwardly, almost nothing visible has changed. Nothing has been lifted. Nothing has been built. Nothing has changed form.

Peter Drucker called this figure the knowledge worker, and the name made perfect sense in 1959.1 It makes less sense now. When Drucker introduced the now-famous term, knowledge itself was still rather scarce. Access mattered. Information moved slowly enough that a skilled professional could realistically absorb a meaningful portion of what mattered in their field. Journals arrived physically in the mail. Reports were typed, copied, and distributed by hand. To know more than your peers often meant literally possessing information they lacked, and much of the difficulty lay upstream in the acquisition process itself. That world is mostly gone now. Today, information is abundant, frictionless, searchable, and permanently available to almost anyone with a phone and an internet connection.

***

In 2026, a knowledge worker can access more material in an afternoon than many researchers could access in months fifty years ago. Large language models can, within seconds, summarize books, explain unfamiliar concepts, generate drafts, search literature, write code, and answer factual questions instantly.

The bottleneck has clearly shifted. An increasingly central form of labor of the information age is no longer acquiring knowledge, but governing the self that must live amid this infinite flood of information.

This is the job description nobody handed you. Your job as a knowledge worker is no longer merely producing output, answering messages, and solving problems, but governing your attention, filtering signals, resisting fragmentation, and beneath it all, reevaluating your own ambitions. Modern life demands all these capacities yet treats them as secondary, optional, private, and nonconsequential. But they are clearly not. For many people, they have become part of the work itself. Choosing what to pay attention to, resisting distraction, managing emotional reactions, recovering from overstimulation, interpreting meaning, and protecting attention from systems designed to fracture it — all of this consumes real energy. This is real work, even if it rarely appears in job descriptions or productivity metrics.

The language of knowledge work describes the handling of external information. It says little about the labor required to maintain the inner conditions from which judgment, clarity, and action emerge in the first place. That deeper layer is what I call mindwork. And a person who does it is a mindworker.

Mindwork is the deliberate labor of regulating, examining, maintaining, and shaping the mind itself.

Not every thought qualifies, and not every moment of reflection deserves the name. Daydreaming is not mindwork. Doomscrolling is not mindwork. Rumination is usually not mindwork either, even when it disguises itself as self-awareness. Genuine mindwork changes the conditions from which future thought and action emerge, while compulsive self-analysis often traps a person inside the same loops they were trying to escape.

***

Mindwork overlaps with several older forms of labor, but it is not identical to them.

Peter Drucker’s knowledge worker primarily handles external knowledge: information is analyzed, transformed, communicated, and applied to real-world problems. The outputs are outward-facing things such as reports, diagnoses, designs, and strategies. In a previous essay, Popper’s Razor, I borrowed Karl Popper’s distinction between the material world (W1), the subjective inner world (W2), and the shared external world of knowledge and culture (W3). Using this language, we can say that knowledge work mostly operates in W3, while mindwork points a lot more toward W2 — the inner layer where attention, interpretation, emotion, identity, and meaning are continuously shaped and negotiated.

Later thinkers pushed beyond Drucker toward ideas like knowledge building and wisdom work. Researchers such as Carl Bereiter and Marlene Scardamalia emphasized the collective creation of genuinely new understanding rather than merely applying existing knowledge.2 More recently, writers like Chip Conley have argued that judgment, discernment, and emotional intelligence are becoming economically central forms of labor in an increasingly automated world.3 Both observations point to something real. Yet even these frameworks mostly culminate outwardly in better knowledge, better leadership, better decisions, and better guidance. Mindwork points one layer earlier and quieter. It concerns the cultivation of the inner conditions from which those outward capacities first emerge.

Knowledge work handles information.
Wisdom work applies judgment.
Mindwork tends the mind that makes both possible.

A few examples make the distinction clearer. A software engineer debugging a production issue is doing knowledge work. The same engineer, noticing that every difficult task triggers avoidance, defensiveness, or compulsive stimulation, then deliberately examines and reshapes those patterns, is doing mindwork. A manager writing performance reviews is doing knowledge work, while the manager realizing halfway through a conflict that her need for control is distorting the conversation is doing mindwork. A writer producing an essay is doing knowledge work, while the writer questioning why he compulsively reaches for productivity systems whenever he feels uncertain about meaning is doing mindwork. The output of knowledge work is external: a document, a design, a strategy, a decision. The output of mindwork is subtler: greater clarity, a revised belief, a weakened compulsion, a healthier emotional pattern, or a more stable relationship to attention itself.

Mindwork is not the same as “mental work” — as a category, mental work is much broader, and almost anything cognitively demanding qualifies, from mental arithmetic to remembering a phone number. Mindwork refers to a specific subset of cognitive work: the deliberate shaping and maintenance of the mind itself. By this definition, a person can of course be a mindworker, knowledge worker, and wisdom worker all at once.

Historically, much inner regulation was scaffolded externally. Religion provided identity and moral structure. Local communities enforced norms and stabilized expectations. Traditions supplied scripts for adulthood, relationships, and meaning, while slower information environments protected attention from continuous extraction. Modern life weakened much of that scaffolding. The individual now performs far more self-governance internally, often without realizing how much labor it requires. Who should I become? What matters? Which ambitions are genuinely mine? Which inputs deserve entry into my attention? Which parts of my identity are inherited, and which are chosen? These questions are no longer philosophical luxuries occasionally asked at midlife. For many people, it is ambient background labor running beneath ordinary workdays.

This is where the modern crisis begins. Many people are already performing enormous amounts of mindwork without recognizing it as work. They experience exhaustion but lack the language to describe it, so they interpret the problem through older categories such as laziness, weakness, poor discipline, insufficient optimization, or lack of motivation. The deeper problem, however, is often unmanaged inner labor.

Three shifts pushed this labor from the margins toward the center of modern life.

First, input became effectively infinite. Modern workers live in an endless stream of messages, feeds, articles, dashboards, podcasts, alerts, recommendations, and generated content, and the challenge is no longer acquiring information but deciding what deserves entry into their attention. That decision is not neutral. Without deliberate inner filtering, the filtering gets outsourced to algorithms optimized for engagement rather than coherence. Attention stops functioning as self-direction and becomes a downstream consequence of someone else’s optimization system.

Second, more output is being automated. Drafts can be generated more readily, summaries produced more readily, code written faster, and images synthesized more completely by systems that process information faster than humans ever could. What remains distinctly human is harder to automate: judgment, interpretation, restraint, ethical orientation, aesthetic taste, long-term coherence, and deciding which questions are worth asking. Those capacities depend less on information itself than on the quality of the mind interacting with it.

Finally, the inner world itself has become contested territory. Modern life mediates attention, identity, emotion, desire, and social reality through systems designed to compete for psychological engagement. Notifications, outrage cycles, feeds, recommendation systems, and infinite entertainment all reach inward. The inner world no longer passively belongs to the individual. It must be defended, maintained, and consciously shaped. Mindwork is the labor of defending inner coherence without collapsing into either fragmentation or endless self-obsession.

***

I slowly began to notice this during my years as a software engineer. On paper, the work did not look especially taxing. I answered messages, attended meetings, reviewed code, wrote specifications, and solved technical problems while sitting at a desk most of the day. Yet I often came home mentally exhausted in a way that felt disproportionate to the visible work itself.

Over time, I realized that part of the fatigue came from another layer running quietly beneath the technical tasks: constant prioritization, emotional regulation, uncertainty, self-monitoring, low-grade background tension, and the ongoing question of what actually mattered amid all the competing demands. Some of that pressure was practical. Some of it was psychological. Some of it was existential. But together, it created a form of inner labor I had never really learned to think about directly.

What changed my relationship to work was not eliminating that layer entirely. Much of it is unavoidable. The change came from recognizing it more clearly, naming some of its patterns, and building structures around it instead of leaving it as undirected weather.

***

Most mindwork involves a small set of recurring moves.

The first is noticing, because you cannot change what you cannot see. Most people move through their inner life half-automatically, reaching for the phone, tightening against criticism, avoiding difficult conversations, and drifting toward distraction without registering the movement itself. Mindwork begins with nothing more dramatic than awareness.

The second move is naming. Once a pattern becomes visible, it can be recognized clearly enough to interrupt. The same anxious spiral before difficult work. The same defensiveness during conflict. The same impulse to escape uncertainty through stimulation or busyness. Naming gives the pattern shape, and things that remain vague tend to remain powerful.

The third move is installing. Mindwork is constructive as well as corrective. Healthier defaults, values, habits, and relationships to attention can be cultivated deliberately over time.

And finally, there is pruning, the slower and more painful process of releasing beliefs, identities, ambitions, and narratives that no longer fit the life around them.

Most productivity systems barely touch any of this. They optimize calendars, task lists, morning routines, and output metrics. Useful things, but downstream things. The deeper question is whether the mind producing those systems is becoming clearer, steadier, and more coherent over time, or merely more optimized inside its own confusion. If the productivity stack runs from aspirations through arcs, programs, projects, and tasks, mindwork sits underneath all of it. It’s the layer that makes every other layer possible.

***

That distinction matters because mindwork has failure modes, too. Not all introspection is healthy. Some people disappear into endless recursive self-analysis where every emotion becomes a puzzle, and every decision becomes identity construction. Some no longer fully live their lives directly because they exist one layer above experience, continuously interpreting, narrating, optimizing, and evaluating it while rarely inhabiting it. The self turns inward so aggressively that contact with reality weakens, and the mind becomes a hall of mirrors.

Healthy mindwork returns a person to clearer action, stronger embodiment, deeper relationships, and greater contact with reality. Unhealthy mindwork collapses into self-consumption.

The goal is not permanent introspection. The goal is maintaining the inner conditions required to live deliberately in environments designed to fragment deliberateness itself. And that is one of the central forms of labor in modern life.

We already have sophisticated language for managing information. We have far less language for managing the mind that must continuously live among it.

Maybe we need some.

My book Scale-Smart Productivity explores in much more depth what changes when inner regulation becomes part of the work itself: proper effort scoping, cultivating aspirations, commitment structures, and the systems required to sustain inner coherence over long periods of time. Find it on Leanpub.

Conley, Chip (2024, August). “Why Wisdom Work Is the New Knowledge Work.” Harvard Business Review. Conley’s framing is broadly compatible with the position taken here, but treats wisdom work as a successor to knowledge work at the same altitude. I’m arguing that mindwork is the deeper layer underneath all three (knowledge work, knowledge building, wisdom work), and that naming it changes how the upper three are practiced.

Name It to Tame It

Dennis Nehrenheim M.Sc. — Tue, 02 Jun 2026 07:52:28 GMT

A while back, I read an intriguing essay by titled The Naming of Things. In it, she argues that the words and metaphors we use for a phenomenon shape our relationship to it. The names we settle on quietly influence what we believe a thing is, what we allow it to do, what responsibilities we attach to it, and what possibilities we can even perceive.

Zoe makes this case using AI and large language models. Are they tools? Assistants? Collaborators? Interfaces? Minds? Each label carries its own assumptions about capability, agency, trust, responsibility, and control. A name is never neutral. It frames the relationship before the relationship even begins.

She is fundamentally right. But the idea reaches further than technology.

The same principle applies inwardly.

The words we use for our own experiences quietly shape our relationship to ourselves. What remains unnamed stays vague and atmospheric. A drifting discomfort. A recurring tension. A heaviness without edges. But once something is named, it changes character. It becomes graspable. It turns from weather into an object. Something you can return to, examine, question, and perhaps even change.

This idea is older than psychology.

In the Grimm tale, Rumpelstiltskin loses his power the moment his name is spoken. In Egyptian mythology, Isis gains dominion over Ra after learning his true name. In A Wizard of Earthsea, magic itself is rooted in true names. To know the name of a thing is to know its nature. Across cultures and centuries, the same pattern keeps appearing: naming creates a strange form of power.

Modern neuroscience hints at something similar. A 2007 UCLA brain-scan study, replicated many times since, showed that putting a feeling into words calms the brain’s alarm system and engages the part that thinks things through.1 The lived experience matches the brain data: naming a feeling makes it easier to carry.

What you cannot name, you cannot properly hold.
And what you cannot hold tends to hold you instead.

It’s like a monster in the dark. Naming the monster weakens it. Not because the monster disappears, but because it moves into a room where you can finally face it.

There’s an echo of all of this in Ludwig Wittgenstein’s famous line:

The limits of my language mean the limits of my world.

That’s the principle I call Name It to Tame It. Before anything in your interior can be tended, examined, released, or grown into something else, it has to be given a name. To name it is to conceptualize it. To name it is to give it a handle. But to name it is even more than that. It is to accept it. To embrace it. Until something has a name, it’s Schall und Rauch — sound and smoke.2 After it is named, it can be worked with.

The most practical example is the stalled task. An item that’s been on your to-do list for weeks. Months. You keep moving it forward, never doing it. The usual suspects — laziness, lack of time — aren’t the cause. The task as written doesn’t name what’s actually there. Vagueness has no handles. The brain skips what it can’t grip. That’s why rewriting a stalled task often dissolves it. You sit with it. You ask what it’s really asking of you. You give it a sharper name. Once the name fits, your hand can find it.3

Much of what I do on this Substack is coining terms and conceptualizing things. Arcs of Aspiration named a layer of life-design that goals don’t reach. The Triple E Game Plan split execution into the three modes it actually contains. The exact terms I land on don’t matter. The things behind them do.

Some of the names you need will be your own, coined for whatever nobody else’s vocabulary quite captures. Others will be borrowed, found in books and conversations that handed you a handle just when you needed one. Both kinds work.

Across the thirty chapters of my book Scale-Smart Productivity, I have named about a hundred such patterns. Some are coined, some borrowed, some old terms with their meaning sharpened. Anomie. Borderlands. Effort Scoping. Friction Pruning. The engagement vs. execution split.

The book is a catalog of handles for the things that most reliably slip. It is on Leanpub, pay-what-you-want. Bring your own monsters.

From Goethe’s Faust. Faust tells Gretchen to call the divine whatever name she likes — Glück, Herz, Liebe, Gott: happiness, heart, love, God. The specific label is interchangeable: Schall und Rauch, sound and smoke. But Faust still offers four names. The essay’s claim is the part Faust leaves implicit: the exact label may be vapor, but having a label is what gives a thing edges.

I’ve written more on the mental visibility of tasks — what makes one item on a list actionable and another invisible — in Selective Task Management.

Popper’s Razor

Dennis Nehrenheim M.Sc. — Tue, 26 May 2026 07:01:09 GMT

Scale-Smart Summary: Some work changes the physical world, like cleaning the dishes. Some happens inside digital systems, like answering email. Some changes your inner world, like committing to a goal. And some creates knowledge that survives beyond you, like publishing an essay. These four “worlds” or work follow different rules, and problems arise when we measure one by the standards of another. Popper’s Razor is a simple heuristic for this problem: before measuring your work, identify the primary world it operates in. The metric follows from the world.

In the early 1970s, philosopher Karl Popper broke with centuries of philosophical tradition. Where most thinkers divided reality into mind and matter, Popper proposed a third world entirely: the world of objective knowledge.

He wasn’t writing about productivity. He was trying to explain how knowledge is able to “escape” the mind. A scientific theory, once written down, no longer belongs only to its creator. Others can criticize it, refine it, reinterpret it, or discover implications its author never saw. Knowledge becomes externalized. It begins to stand on its own.

I’ve found this framework surprisingly useful for understanding modern work. Much of my book builds on it. But here I want to focus on one specific application: how different kinds of work require different kinds of measurement.

Three Worlds

Popper’s three worlds can be outlines as follows:

World 1 (W1) is the material universe. Atoms, objects, bodies. Your kitchen, your muscles, the coffee going cold on your desk. Anything you can touch.

World 2 (W2) is the separate world of subjective experience. Thoughts, emotions, beliefs, memories. The interior. This is where reflection happens, where you wrestle with your mindset, where mental visibility lives. Internal, private, entirely yours.

World 3 (W3) is the world of objective, mind-independent knowledge. Ideas, theories, books, laws, cultural artifacts. Products of the mind that, once externalized, take on a life of their own — they can carry implications even their creators never noticed.

For a productive life, these worlds matter because different kinds of work break down under different metrics. Physical chores (W1) suffer when overcomplicated with reflection or optimization. Reflection (W2) suffers from throughput measurement. Knowledge work (W3) suffers under constant responsiveness.

My argument is that much professional frustration comes from measuring one kind of work by the standards of another. And that’s exactly where Popper’s philosophy can help.

Popper’s Razor

Different worlds or work require different standards. But once the dominant world becomes clear, many misleading metrics fall away automatically. That’s how we end up with the heuristic I call Popper’s Razor: Before measuring work, first identify what kind of work it primarily is. I call this Popper’s Razor because, like Occam’s Razor, it cuts. Occam shaves off unnecessary entities. Popper shaves off the wrong measures.

So, to recap, Popper’s Razor is simply this: identify the primary world your work operates in, then prioritize metrics appropriate to that world, and treat all other possible metrics as secondary constraints or supporting inputs.

Most work touches several worlds at once. The goal is not perfect classification, but avoiding distortion. Let’s look at an example: dishwashing. Physically, it’s W1 work. Plates become clean. The metrics are obvious: plates cleaned, time elapsed, and completion. Did the kitchen get cleaned? How long did it take?

But now imagine someone using dishwashing as a mindfulness exercise. The physical task remains W1, but the primary aim shifts to W2 — presence, attentional stability, internal stillness. Measuring it solely by speed would undermine the point.

Imagine a third case. Someone experiments with cleaning methods, documents the results, and publishes an essay about efficient household systems. The activity now substantially participates in W3. The relevant question: did something useful or durable emerge that others can build upon?

Same activity. Different evaluative center. The dominant intention changes how the work should be measured.

**W1* — The Digital Layer**

In my work I make one important addition to the three worlds: W1*, the digital world. Platforms, files, feeds, dashboards, Slack threads, APIs, profiles, algorithmic systems, virtual environments — the strange operational layer where modern knowledge work increasingly happens. I separate it from physical reality because digital systems create their own forms of confusion. A cluttered garage and a cluttered Slack workspace do not behave the same way, even if both are forms of disorder.

In W1*, replication is nearly free. Storage feels infinite. Identities fragment across platforms. Communication becomes asynchronous and ambient. Unfinished work accumulates invisibly. Responsiveness masquerades as productivity. Information moves faster than embodied cognition can comfortably process.

W1* is less a separate metaphysical realm than a distinct operational environment with its own pressures, incentives, and cognitive traps. Most modern knowledge workers now spend large parts of their lives inside it.

Different Worlds, Different Measures

The four worlds overlap. Most meaningful work touches several at once. But the importnat thing is that there is usually one dominant intention behind the activity, and that intention determines which metrics matter most. This is the core idea behind Popper’s Razor: before measuring work, first identify the world the work primarily operates in. The metric follows.

Each world rewards different things. W1 rewards observable outputs. Did the package ship? Did the kitchen get cleaned? W1* rewards information flow and decision velocity. Did this communication clarify, or multiply confusion? W2 rewards presence and clarity. Did I think more clearly today? W3 rewards understanding others can build upon. Will this still matter in five years?

The metrics aren’t interchangeable. Ask a W1 question of W3 work and the work looks like nothing got done. Ask a W3 question of W1 work and the work looks pointless. The razor cuts the mismatch before it starts.

Two Questions

Before the work begins: what world is primary here?

Then, once the work is underway: Am I using proper metrics for this world?

Together, these questions dissolve surprising amounts of confusion. Not because the four worlds are perfectly clean categories, but because different forms of work break down under different forms of measurement.

Popper’s Razor is one of the most important conceptual tools sitting inside Scale-Smart Productivity, the book I’m publishing on Leanpub.
