John Naish published Enough in 2008, a year before the word "enoughness" had entered the cultural conversation. Reading it now, the prescience is striking. Naish — a science journalist for The Times — draws on evolutionary biology, consumer psychology, and neuroscience to argue that the human brain's default setting of "more" was adaptive for hunter-gatherers but is profoundly maladaptive in a world of unprecedented abundance. The antidote, he argues, is not deprivation but the cultivation of a skill our ancestors never needed: the ability to recognise when we have enough.
What Is This Book?
Naish structures the book around specific domains of “more-ness”: more stuff, more food, more information, more work, more happiness. In each domain, he traces the evolutionary origins of the drive for more, documents the research on what happens when that drive is chronically satisfied without limit, and suggests what “enoughness” might look like in practice. The book is equal parts cultural critique and self-help, and the balance works better here than in most books that attempt it.
The Evolutionary Argument
Naish’s central insight is that the human drive for more was shaped in an environment of scarcity — where wanting more food, more security, more social status had direct survival value. In a modern environment of abundance, that same drive has become a runaway process with no natural off-switch. We are, in his phrase, “victims of our own success” — equipped with desires calibrated for a world that no longer exists and unable to feel satisfied by abundances our ancestors could never have imagined.
Our brains were designed to never be satisfied — because in our evolutionary past, dissatisfaction was survival. In a world of abundance, that same dissatisfaction has become a disease.

Where It Gets Practical
The most actionable chapters are on information and work. Naish’s analysis of information overload — written before smartphones, before Twitter, before 24-hour news became a universal experience — reads as strikingly contemporary. His suggestions for information fasting and attention management predate and anticipate much of the current “digital wellness” literature. The chapter on work challenges the productivity mythology that equates busyness with value and presents research on the diminishing returns of overwork on creativity and wellbeing.
6 Key Ideas From This Book
The human drive for more — more food, resources, status, information — was adaptive in conditions of scarcity. In abundance, the same drive produces chronic dissatisfaction because it was never designed to be satisfied.
Recognising sufficiency does not come naturally to humans — it must be consciously cultivated. Like any skill, it requires practice, and the culture actively discourages it through advertising, social media, and status signalling.
The human attention system was not designed for the volume of information modern life produces. Chronic overexposure degrades decision-making, creativity, and wellbeing — not just comfort and focus.
The "happiness industry" — self-help, positive psychology, the pursuit of peak experiences — can itself become another form of chronic wanting. Naish argues for contentment over the relentless pursuit of happiness.
Research consistently shows that beyond 40–50 hours per week, additional work produces diminishing returns on output and accelerating returns on error, illness, and burnout. "More work" is often less work.
In a culture built on perpetual growth and want-creation, choosing sufficiency is genuinely countercultural. Naish frames enoughness not as resignation but as resistance — the most subversive act available to a modern consumer.
Any Weaknesses?
Written before smartphones transformed information overload into its current intensity, some of the information-chapter examples feel dated — though the underlying argument remains valid. The book’s British cultural references also occasionally require translation for non-UK readers. And Naish’s prescriptions, while sensible, are sometimes vague — he is better at diagnosing the problem than specifying the cure.
Who Should Read This?
Readers who want the evolutionary and scientific case for why more never feels like enough, rather than just practical decluttering tips or lifestyle advice.
Stuffocation by James Wallman for a more contemporary cultural analysis, or The Year of Less by Cait Flanders for a personal narrative of consumption reduction in practice.
Economists and policy makers — Naish's challenge to perpetual growth as an economic organising principle has relevance far beyond personal lifestyle choices.
A book that is better at analysis than prescription. Naish explains why we want more with great clarity; his solutions are less developed than his diagnosis.
Frequently Asked Questions
Is Enough worth reading?
Enough is the intellectually rigorous foundation that most simplicity books lack — it explains why we want more, not just why we should want less. Naish's evolutionary framework is genuinely illuminating and his information overload chapters are prescient. A valuable complement to the more personal, practical books in the Simple Living genre.
