The Reading Habit of Effective Leaders: Why It Matters More Than Ever

Referenced: Where is Your Why?: A Formula of Building Blocks to Attain Success

There is a question I ask senior executives early in advisory engagements that I have come to consider one of the most diagnostic questions in leadership: what are you reading? Not articles. Not summaries. Not what you skimmed in airport lounges. What books are open on your nightstand right now, and what are they teaching you?

The pattern in the answers is striking. The leaders whose careers continue to deepen and whose organizations continue to evolve almost always have a serious reading practice. The ones who have plateaued, often invisibly, have usually stopped reading anything substantive. They consume executive summaries. They listen to podcasts at 1.5x. They scan LinkedIn posts. None of which is bad. But none of which builds the kind of layered, slowly-accumulated thinking that distinguishes a wise leader from an informed one.

Information Versus Understanding

We are drowning in information and starving for understanding. Information is what arrives in your inbox, your news feed, your podcast queue. It is fast, abundant, and forgettable. Understanding is what builds slowly, over years, through sustained engagement with the best thinking on a subject. It is what allows you to recognize patterns when they recur. It is what gives you frameworks robust enough to handle situations you have never faced before.

In Where Is Your Why?: A Formula of Building Blocks to Attain Success, I argue that purposeful living is built through deliberate practices—and one of the most consequential is the practice of feeding your mind something more substantial than what the algorithms are serving you. The leaders who do this consistently develop a quality of judgment that is difficult to acquire any other way.

What to Read

The temptation, especially for busy executives, is to read only books that are immediately useful. The latest leadership tactics. The current strategy frameworks. The trending business memoir. There is value in some of that, but a diet composed entirely of immediately-useful reading produces a thinker whose framework is whatever was popular in the last five years. Useful in the short term. Limited in the long run.

The most thoughtful leaders I know read across four categories:

Foundational texts in their domain. The classics that established the field. Drucker on management. Christensen on disruption. Heifetz on adaptive leadership. These books reward the time investment because they have already passed the test of decades.

History and biography. Reading about leaders and organizations from other eras provides pattern recognition that is impossible to develop by only reading about your own time. The challenges leaders face today are not as unprecedented as the news cycle suggests. Most of them have been faced before, in different forms, and the historical record is full of useful lessons.

Adjacent disciplines. Cognitive science. Behavioral economics. Anthropology. The natural sciences. The breakthrough insights in any field often come from importing frameworks from a different field. Reading widely outside your specialty is one of the most reliable ways to develop original thinking.

Fiction and literature. The category most executives skip, and the one that may matter most. Great fiction develops empathy, sharpens observation of human behavior, and trains the mind to hold complexity. The best novels teach you about people in ways that no business book can.

How to Read

The mechanics of reading matter as much as the selection. A few principles that consistently differentiate serious readers from occasional ones:

Read on paper, mostly. The research on retention and comprehension is clear: reading on paper produces better understanding and better recall than reading on screens, especially for difficult material. Save your screen time for the email, news, and entertainment that does not deserve your full attention.

Read with a pen. Mark up books. Underline. Write in the margins. Disagree with the author in writing. The act of marking what you read transforms passive consumption into active engagement, and active engagement is what produces lasting understanding.

Re-read the best books. A great book read three times across a decade will teach you more than thirty different books read once. The Dao De Jing read at thirty is a different book at fifty. So is Marcus Aurelius. So is any work of real depth. The leaders with the most refined judgment often have a small canon they return to repeatedly.

Take notes that you will revisit. A reading practice without a note-taking practice produces ideas that evaporate. Develop a system—commonplace book, digital notes, index cards—where the most valuable passages and ideas live. Review your notes periodically. The compounding is significant.

When to Read

The most common excuse I hear for not reading is time. "I would love to read more, but I just do not have the time." This is almost always inaccurate. The same executives who claim no time for reading have plenty of time for low-value activities: scrolling, checking, switching, refreshing. The question is not whether you have time. It is whether you have the discipline to allocate the time you have.

Thirty minutes a day, every day, produces real depth over a year. That is roughly twenty books, depending on length and difficulty. Twenty books a year, sustained for a decade, is two hundred books—an education that cannot be acquired any other way. The executives who build this habit early in their careers have an advantage by their forties that their peers struggle to close.

Where the thirty minutes come from is a personal decision. For most leaders I know, it is early morning before the day starts, or late evening after it ends. Some carve out reading time during travel. Others have a standing policy of reading instead of scrolling at any moment of unstructured time. Whatever works—the key is that it becomes non-negotiable, like exercise or sleep.

The Compounding Effect

The dividends of a serious reading practice are not visible in any given week. They become apparent in years. The leader who has read deeply across decades makes connections that surprise their peers. They have language for situations that others can only describe vaguely. They draw on a wider range of analogies and frameworks. They are calmer in disruption because they have read about leaders in worse disruption who navigated through it.

None of this is academic. It shows up in the boardroom, in the difficult conversation, in the strategic choice that has to be made with incomplete information. The leader who has been thinking carefully about leadership for thirty years, through hundreds of books and countless conversations, brings something to those moments that the leader who has read fifty business books and listened to a thousand podcasts simply cannot match.

An Invitation

If you have not had a serious reading practice in a while, the way back is small. Pick one book that has been on your list for years. Buy a paper copy. Read it for thirty minutes a day, with a pen in hand. See how you feel at the end of it.

The leaders who build my online courses into their development plan often tell me that the most valuable shift was not the new framework. It was reactivating a reading habit they had let lapse. Once that habit comes back, everything else accelerates.

The organizations you lead deserve a leader who is still growing. The reading is how you make sure that is true.
