The Diary of a CEO Review: 33 Laws, Strong Ideas, and Where to Be Skeptical
Steven Bartlett packages business and life lessons as 33 durable laws. The format is highly readable. The right way to use it is as a set of hypotheses to test—not commandments to obey.

The short review
Engaging and practical when treated as a toolbox. The main risk is turning memorable language into universal truth without testing it.
This The Diary of a CEO review is not a chapter-by-chapter recap. The goal is to judge this specific book as a decision tool: what problem it helps solve, where its framework is strong, where it can mislead, and what a reader should actually do after closing it.
What the book is about
The publisher and author describe the book as a set of principles intended to outlast changing business tactics. That framing is sensible: distribution channels, software, and platforms change quickly, while incentives, storytelling, learning, teams, attention, and human behavior change more slowly.
That distinction matters for The Diary of a CEO. The useful test is not the number of ideas on the page, but whether this book changes the quality of a decision, creates a better question, exposes a hidden trade-off, or produces behavior that can survive contact with reality.
What it gets right
It is designed for recall
A principle-based structure gives readers mental handles. In practice, a memorable rule can be more useful than a sophisticated idea you cannot retrieve when a decision arrives.
It connects business performance to human behavior
Leadership rarely fails only because a spreadsheet was wrong. Communication, ego, incentives, trust, hiring, persuasion, resilience, and attention all matter. Bartlett’s broad lens reflects that reality.
It encourages experimentation
The best way to read 'laws' is experimentally. Take one, define what it predicts, apply it in a bounded context, and measure what changes. That transforms an inspirational principle into operating knowledge.
Where to be skeptical
- Calling principles 'laws' can make contingent advice sound more universal than it is. Context matters, especially across industries, cultures, company stages, and power structures.
- Founder stories are memorable but can create survivorship bias. A compelling anecdote should generate a hypothesis, not close the case.
These limitations do not invalidate The Diary of a CEO. They define its boundary conditions. The framework becomes more useful when you know the situations in which this particular book should not be trusted by itself.
Who should read it?
Best for ambitious generalists, founders, creators, managers, and young professionals who prefer short, memorable principles over a single deep technical framework.
Who should skip it?
Less useful if you want rigorous treatment of one narrow field such as finance, operations, or organizational psychology.
How to apply the book instead of just finishing it
- Choose three laws that address a current business constraint rather than reading all 33 as equal priorities.
- Convert each chosen law into one observable behavior or experiment.
- Record where the principle fails; boundary conditions are as useful as successes.
- Review results monthly and keep only what improves decisions, execution, or relationships.
When applying The Diary of a CEO, resist extracting twenty ideas. Pick one decision, one behavior, and one measurable experiment. This book becomes valuable when it changes what you do, not when it merely expands a notes folder.
