Open the calendar of a senior executive and it looks brutally efficient. Meetings are stacked like Tetris blocks, fifteen-minute gaps colonised by “quick calls”, travel time reduced to a logistical puzzle. And yet, talk privately to many of those same leaders and they will mention a quieter, less visible discipline that survives even the busiest weeks: reading. Not scanning headlines, but sustained engagement with books that demand time, patience, and attention.

Bill Gates has long been open about reading roughly 50 books a year. Warren Buffett reportedly spends up to 80 per cent of his working day reading. Others, from tech founders to industrial CEOs, make similar claims.

At first glance, this seems faintly unreasonable. Who, exactly, has the time? Modern executives are already drowning in emails, dashboards, meetings, and “urgent” notifications. Yet reading persists, not as a nostalgic habit from a pre-digital age, but as a deliberate professional advantage. And not just reading business books, but history, psychology, science, fiction, biography – the whole span of the library.

The reason is simple. In a world where information is abundant, insight is scarce. Reading remains one of the most reliable ways to develop it. Not because it feels efficient, but because it quietly improves the one thing leadership depends on most, how people think.

Here are seven reasons why reading retains such power for business professionals, alongside practical guidance on how to make it work in an already overflowing schedule. You can turn reading into a habit rather than a guilty intention.

1. Reading Builds Better Judgment, Not Just Knowledge

Leadership is less about having the right answer and more about making good decisions under uncertainty. Reading helps by quietly expanding the number of mental models leaders can draw upon. When Buffett talks about reading, he often frames it as compounding: each book adds a small edge, but over time those edges stack up.

This is especially true when reading beyond one’s immediate field. A supply chain disruption may look very different after reading economic history. A people problem takes on new texture after psychology or sociology. Reading teaches pattern recognition, which is the backbone of sound judgment.

Unlike short-form content, books force sustained engagement. They resist skimming, and that resistance is precisely the point.

Our BlueSky Thinking book recommendation – The Most Important Thing by Howard Marks.

This short, deceptively simple book is really about judgment under uncertainty. It explores second-level thinking, risk, and the dangers of consensus – skills that translate far beyond investing. Many CEOs value it precisely because it teaches how to think rather than what to think.

2. Reading Strengthens Strategic Thinking by Slowing the Mind

Modern business culture prizes speed. But strategy often suffers when thinking becomes reactive. Reading, by its nature, slows cognition down, encouraging reflection rather than reflex.

Long-form arguments help leaders grapple with trade-offs, second-order effects, and unintended consequences. This is one reason many executives return repeatedly to books on history and geopolitics. Strategy, after all, is rarely new. It is old dilemmas wearing new clothes.

Reading creates space to think before acting – an increasingly rare but valuable leadership capability.

Our BlueSky Thinking book recommendation – Thinking, Fast and Slow by Daniel Kahneman.

The Nobel laureate explores how our minds use two systems for thinking in his bestseller. System 1 is fast, intuitive, and emotional for quick judgments, and System 2 is slow, logical, and effortful for complex problems. 

His book takes an average of 10 to 12 hours to read, but many suggest taking weeks or months to absorb the dense material, often reading 1-2 chapters daily to grasp complex concepts and experiments, given its 500 pages of deep insights. 

3. Reading Expands Empathy and Emotional Intelligence

It may surprise some spreadsheet-inclined executives, but one of the strongest arguments for reading lies in empathy. Research in psychology has consistently shown that reading literary fiction, in particular, improves the ability to understand other people’s perspectives.

For leaders managing diverse teams across cultures, functions, and generations, this matters. Fiction allows readers to inhabit minds unlike their own. Biographies reveal the messy human reality behind polished success stories. Even well-written non-fiction exposes the emotional undercurrents beneath rational decisions.

In an era where leadership credibility depends increasingly on trust, this emotional range is not optional.

Our BlueSky Thinking book recommendation – Never Let Me Go by Kazuo Ishiguro

At first glance, an unusual recommendation for business leaders. But Ishiguro’s novel is a masterclass in perspective-taking, moral ambiguity, and quiet emotional awareness. It lingers precisely because it forces readers to sit with discomfort and unspoken assumptions.

4. It Improves Communication (Including the Ability to Think Clearly)

Reading and writing are close cousins. Leaders who read widely tend to speak and write more clearly, not because they memorise elegant phrases, but because they learn how ideas are structured.

Exposure to good writing sharpens thinking. It teaches how arguments are built, how evidence is weighed, and how complexity can be explained without distortion. This shows up in boardrooms, investor calls, and internal communications alike.

Put bluntly, leaders who read tend to sound like they know what they’re talking about – because they often do.

Our BlueSky Thinking book recommendation – On Writing Well by William Zinsser

Zinsser’s classic is nominally about writing, but its deeper lesson is about thinking with clarity and honesty. Many executives discover that improving how they write dramatically improves how they structure arguments, presentations, and strategy documents.

5. Reading Fuels Creativity Through Eclectic Inputs

Innovation rarely comes from staying inside one intellectual lane. Many CEOs who champion reading emphasise variety rather than volume. Gates, for instance, alternates between science, global health, economics, and memoir.

This eclecticism matters because creativity thrives on unexpected connections. A book on biology may spark a new organisational metaphor. A novel may inspire a product story. Reading across domains increases the chance of productive collisions between ideas.

The value lies not in immediate applicability, but in long-term cognitive flexibility.

Our BlueSky Thinking book recommendation – Range: Why Generalists Triumph in a Specialized World by David Epstein

Epstein makes the evidence-based case that breadth often outperforms narrow specialisation in complex, unpredictable environments. The book resonates strongly with leaders navigating innovation, talent development, and long-term strategy.

6. It Offers Perspective in Times of Pressure

Every leadership role eventually involves crisis. Markets turn. Strategies fail. Public scrutiny intensifies. Reading provides something surprisingly practical here: perspective.

History reminds leaders that today’s “unprecedented” challenges are often less unique than they feel. Biography shows that admired figures stumbled repeatedly. Philosophy encourages reflection on what truly matters when incentives collide.

This perspective does not eliminate stress, but it contextualises it. And that alone can change how leaders respond.

Our BlueSky Thinking book recommendation – Meditations by Marcus Aurelius

A collection of personal writings by a Roman emperor managing war, plague, and political intrigue, Meditations has become a quiet favourite among modern CEOs. Its appeal lies in its restraint: reminders about control, humility, and impermanence.

7. Reading Is One of the Few Solitary Leadership Practices That Scale

Unlike coaching or offsites, reading scales indefinitely. It is available on flights, in hotel rooms, and during otherwise wasted fragments of time. It requires no approval, no budget line, and no facilitation.

Most importantly, it compounds quietly. No one applauds a leader for finishing a book, yet its influence often shows up months later in better questions, calmer decisions, and clearer priorities.

Our BlueSky Thinking book recommendation – The Power Broker by Robert Caro

Caro’s monumental biography of Robert Moses is long, demanding, and utterly absorbing. Leaders who tackle it often cite not just what they learned about power, but the discipline required to engage deeply with a complex narrative over time.

How to Fit Reading into an Already Busy Schedule

The most common objection to reading is not philosophical; it is practical. The trick is to stop treating reading as a leisure activity that requires large, uninterrupted blocks of time.

Successful readers do three things differently:

First, they lower the activation energy. Books are kept within reach: on phones, tablets, bedside tables, and desks. The easier it is to start, the more likely it happens.

Second, they use transitional time. Flights, train journeys, early mornings, and even the last ten minutes before sleep are reclaimed from digital drift or a Korean Netflix drama..

Third, they abandon books without guilt. Finishing is optional. Extracting value is not. Leaders who read a lot are ruthless about stopping when a book no longer delivers insight.

Audiobooks also deserve a special mention. For many executives, they transform commuting and exercise into reading time without competing with work hours.

Which Books Should Business Professionals Prioritise?

Rather than chasing “must-read” lists, effective readers choose books across three overlapping categories:

1. Books aligned with what you want to learn. These include strategy, leadership, technology, economics, or industry-specific works. For example, Thinking, Fast and Slow mentioned earlier remains influential for understanding decision-making biases in business.

2. Books driven by curiosity and eclectic stimulation. History, science, philosophy, and fiction belong here. They may not map directly onto today’s KPIs, but they stretch thinking in unexpected ways.

3. Books that challenge your worldview. This category is the most uncomfortable, and often the most valuable. Reading arguments you disagree with sharpens reasoning and reduces intellectual complacency.

A balanced reading diet across all three prevents both narrow expertise and unfocused wandering.

Three Tips for Making Reading a Lasting Habit

1. Attach reading to an existing routine. Rather than scheduling “reading time,” link it to something already habitual: morning coffee, evening wind-down, or weekly travel.

2. Keep a simple reading log. Not for productivity points, but for reflection. A few lines on what resonated, or irritated helps convert reading into insight.

3. Talk about what you read. Discussing books with colleagues, book clubs, or even LinkedIn posts reinforces learning and accountability. Ideas grow when shared.

The Quiet Competitive Advantage

In a business culture obsessed with acceleration, reading can feel almost subversive. It produces no immediate metrics and resists optimisation. Yet that is precisely why it endures.

Reading trains leaders to think beyond the quarterly cycle, to see patterns before they become obvious, and to approach decisions with humility rather than haste. It is not a guarantee of wisdom, but it remains one of the most reliable paths toward it.

Perhaps that is why so many of the world’s most successful leaders keep returning to books. Not because they have time to read, but because they understand something more important: they cannot afford not to.
