Journaling Like Marcus Aurelius: The Stoic Art of Writing to Yourself

The most powerful man in the ancient world sat down each evening and wrote to himself. Not dispatches to generals, not decrees for the empire, not letters to the Senate. Marcus Aurelius, Emperor of Rome from 161 to 180 CE, wrote private notes reminding himself how to be a better person. He admonished himself for laziness. He rehearsed philosophical principles. He worked through anger, frustration, and fear on the page. He never intended for anyone else to read these notes.

Those private writings became Meditations, one of the most influential philosophical texts in Western history. But what makes Meditations remarkable is not just its content — it is the method behind it. Marcus did not write a treatise or a textbook. He developed a daily journaling practice that served as a form of philosophical therapy, a way of training his mind to respond to the world with clarity, virtue, and composure.

This guide will show you how that practice worked, why it remains relevant, and how to build your own Stoic journaling habit.

How Marcus Used Journaling as Philosophical Practice

To understand Stoic journaling, you first need to set aside the modern concept of a diary. Marcus was not recording his meals, documenting his activities, or venting his emotions for cathartic release. He was doing something more targeted: he was applying Stoic philosophy to the specific circumstances of his day.

Every entry in Meditations is an exercise. Marcus takes a Stoic principle — the impermanence of all things, the importance of focusing on what is within his control, the duty to act with justice and compassion — and works it through the lens of whatever he was facing at that moment. He was not philosophizing in the abstract. He was doing philosophy the way a musician practices scales: repetitively, deliberately, with the goal of building the skill so deeply into muscle memory that it becomes automatic.

This is what the French philosopher Pierre Hadot, in his landmark study The Inner Citadel, called “spiritual exercises.” Hadot argued that ancient philosophy was never meant to be purely theoretical. It was a set of practices designed to transform the practitioner — and journaling was one of the most important tools in that process.

Marcus did not write to create literature. He wrote to change himself.

The Structure of Meditations: Writing to Himself, Not to Us

One of the most striking features of Meditations is its form. Unlike nearly every other major philosophical text, it was never intended for publication. There is no audience, no argument structured for persuasion, no attempt to build a systematic case. Instead, we find repetition, self-correction, and the kind of raw honesty that only appears when someone is truly talking to themselves.

Marcus returns to the same themes over and over. The impermanence of fame. The shortness of life. The importance of not being disturbed by things outside his control. He does not repeat himself because he has forgotten what he already wrote. He repeats himself because the lessons need constant reinforcement. Knowing a principle intellectually and living it are two entirely different things, and the gap between them is where journaling does its work.

The entries range from single sentences to extended meditations spanning several paragraphs. Some are direct commands to himself. Others are observations about nature, time, or human behavior that lead to ethical conclusions. Many take the form of what we might now call cognitive reframing — taking a troubling situation and redescribing it in terms that reveal a better response.

For example, when Marcus was frustrated with the people around him, he did not simply write “I am angry.” He worked through the anger on the page: these people act from ignorance, not malice; they share in the same rational nature that I do; my frustration harms me more than their behavior does; my job is not to change them but to respond with justice. By the time he finished writing, the anger had been processed — not suppressed, but genuinely transformed through philosophical reasoning.

Hadot’s Three Disciplines: A Framework for Stoic Journaling

Pierre Hadot identified three “disciplines” that structure Marcus’s writing, corresponding to the three branches of Stoic philosophy: logic, physics, and ethics. Understanding these disciplines gives you a powerful framework for your own journaling practice.

The Discipline of Desire (Physics)

This discipline is about aligning your desires and aversions with the nature of reality. Entries in this category deal with acceptance — accepting that things are impermanent, that events outside your control will not always go your way, and that the universe operates according to patterns you cannot override.

When Marcus writes about the vastness of time, the smallness of individual human concerns, or the cyclical nature of all things, he is practicing the discipline of desire. He is training himself to want what is actually possible and to stop craving what is not.

Journal prompt: What happened today that I wished had gone differently? Was the outcome within my control? If not, can I practice accepting it as part of the natural order of things?

The Discipline of Action (Ethics)

This discipline is about acting justly and serving the common good. Entries in this category deal with duty — your obligations to others, the importance of acting with integrity even when it is difficult, and the Stoic conviction that human beings are meant to work together.

When Marcus reminds himself to be patient with difficult people, to act for the benefit of the community, or to fulfill his responsibilities despite exhaustion, he is practicing the discipline of action. He is aligning his behavior with the four Stoic virtues: wisdom, courage, justice, and temperance.

Journal prompt: Did I act justly today? Was there a moment when I chose convenience over integrity? How can I respond better tomorrow?

The Discipline of Assent (Logic)

This discipline is about examining your initial impressions and judgments before accepting them as true. Entries in this category deal with perception — questioning whether your emotional reactions are based on reality or on distorted interpretations.

When Marcus catches himself adding unnecessary value judgments to neutral events (“this is terrible,” “this is unfair”), he is practicing the discipline of assent. He is pausing between the event and his response to check whether his interpretation is accurate.

Journal prompt: What strong emotional reaction did I have today? What was the impression that triggered it? When I examine that impression closely, is it accurate, or did I add something that was not there?

How to Start a Stoic Journal

Starting a Stoic journaling practice does not require special equipment, extensive training, or large amounts of time. Here is a practical guide for building the habit from scratch.

Choose Your Format

Marcus wrote on papyrus or wax tablets. You have more options. The key is to choose a format that you will actually use consistently.

Physical notebook: Many practitioners prefer a dedicated notebook. The act of writing by hand slows your thinking and creates a different relationship with the words than typing does. A simple, sturdy notebook is all you need — nothing fancy. If you want a notebook designed for reflective practice, consider a dedicated journal like the ones paired with The Daily Stoic by Ryan Holiday.

Digital tools: If you prefer typing, a simple notes app, a text file, or a dedicated journaling app works fine. The advantage of digital journaling is searchability — you can easily review past entries for patterns. The disadvantage is the temptation to browse the internet instead of writing.

Commonplace book: Ryan Holiday has popularized the practice of keeping a commonplace book — a notebook where you collect quotes, ideas, and reflections from your reading. This pairs well with Stoic journaling. You might keep a section for passages from Stoic texts and another for your own reflections on how those passages apply to your life.

Choose Your Time

Marcus appears to have written primarily in the evening, reflecting on the events of the day. This aligns with the Stoic practice of the evening review, in which you examine your day’s actions against your philosophical principles.

However, morning journaling also has strong Stoic roots. Marcus’s famous passage about anticipating difficult people was clearly a morning exercise — a preparation for the day ahead rather than a review of one already completed.

You can practice either or both. Many people find that a brief morning session (5-10 minutes of setting intentions and reviewing principles) combined with a longer evening session (10-20 minutes of reflection and self-examination) works best. But even one session per day is vastly better than none.

Use Prompts Until You Don’t Need Them

When you are starting out, a blank page can be intimidating. Prompts provide structure until the habit becomes natural. Here are prompts organized by the three Hadot disciplines:

Desire (Acceptance and Impermanence):

• What am I clinging to that I cannot ultimately control?
• What would I do differently if I truly accepted that this situation is temporary?
• How does today’s frustration look from the perspective of a year from now? A decade?

Action (Virtue and Duty):

• Where did I fall short of my own standards today?
• Who did I help, and who could I have helped but chose not to?
• What is the most important thing I am avoiding, and what would courage look like?

Assent (Judgment and Perception):

• What story am I telling myself about this situation? Is it true?
• Am I reacting to what actually happened, or to what I imagine it means?
• What would a wise person think about this?

As you build the habit, you will find that you need prompts less and less. Your own day will provide the material, and the framework will become instinctive.

Sample Entries for Common Life Situations

To make this concrete, here are examples of what Stoic journal entries might look like for situations you are likely to face. These are written in the second person, as Marcus wrote to himself.

After a Conflict at Work

“You let your temper get the better of you in the meeting today. What did that accomplish? Nothing. The other person was operating from their own perspective, shaped by their own experiences and fears. You cannot control how they behave — only how you respond. Next time, pause before speaking. Ask yourself: what does justice require here? Not victory, not being proven right, but justice. Speak from that place or do not speak at all.”

After Receiving Bad News

“The test results are not what you hoped for. Notice the impulse to catastrophize, to spin out every worst-case scenario. This is your imagination running ahead of reality. Right now, in this moment, you are sitting in a chair, breathing, alive. Deal with what is actual, not what is imagined. What is the next right step? Take that step. Then take the next one.”

On a Day When You Feel Unmotivated

“You do not feel like working today. So what? The horse does not feel like pulling the cart. The vine does not feel like bearing grapes. They do what they were made to do. You were made for work — not just labor, but meaningful contribution to the people around you. Get up. Start with the smallest task. Motivation follows action, not the other way around.”

After Comparing Yourself to Others

“You spent twenty minutes envying someone else’s success. Twenty minutes you will never get back, spent on something entirely outside your control. Their achievements are theirs. Your work is yours. Return to your own field and tend it. As Marcus wrote, what harm have you done yourself with those thoughts?”

The Science of Expressive Writing

Modern research supports what Marcus discovered through practice. Psychologist James Pennebaker has spent decades studying the effects of expressive writing — the practice of writing about your thoughts and feelings surrounding significant events. His findings are consistent and striking.

People who engage in regular expressive writing show measurable improvements in physical health, immune function, emotional well-being, and even professional performance. The mechanism appears to be similar to what the Stoics observed: writing forces you to organize chaotic thoughts into coherent narratives, which reduces the cognitive and emotional burden of unprocessed experience.

Pennebaker’s research also found that the most beneficial writing goes beyond simple emotional venting. The entries that produce the greatest improvements are those that involve meaning-making — the attempt to understand why something happened and what it means for how you should live going forward. This is precisely what Marcus does in Meditations. He does not just express frustration; he works through it to reach a philosophical conclusion that guides future behavior.

The parallel is striking: modern psychology has independently validated the approach that a Roman emperor developed through Stoic practice nearly two thousand years ago.

Common Mistakes and How to Avoid Them

Treating It as a Performance

Your Stoic journal is for you. The moment you start writing for an imagined audience — even an audience of one future self who might judge you — you lose the honesty that makes the practice valuable. Write badly. Write messily. Contradict yourself. The quality of the prose is irrelevant. What matters is the quality of the thinking.

Expecting Instant Results

Marcus wrote in Meditations for years, possibly decades. He returned to the same lessons hundreds of times. If you expect a single journal entry to permanently resolve a deep-seated emotional pattern, you will be disappointed. The practice works through accumulation, not revelation. Trust the process.

Skipping the Hard Stuff

The entries you least want to write are usually the ones you most need to write. When you notice yourself avoiding a topic — a failure, a fear, a relationship problem, a moral compromise — that is a signal, not a stop sign. The Stoic journal is where you face things honestly, not where you curate a flattering self-image.

Making It Too Complicated

You do not need a special system, a color-coded methodology, or a dozen different journals. Marcus used whatever was available. The best system is the simplest one you will actually use. One notebook, one pen, ten minutes. That is enough.

For a structured approach to building this alongside other Stoic habits, A Handbook for New Stoics by Massimo Pigliucci and Gregory Lopez offers a 52-week program that includes journaling exercises alongside other practices.

Beyond the Page: Journaling as a Way of Life

The ultimate goal of Stoic journaling is not to fill notebooks. It is to internalize the philosophical perspective so deeply that it becomes your default way of seeing the world. Marcus did not need to write in his journal during a crisis. The years of practice had trained his mind to think like a Stoic automatically — to pause before reacting, to examine his impressions, to consider what virtue required, to remember that this too would pass.

The journal is the training ground. Life is the arena.

Over time, you will notice that the principles you write about in the evening start appearing in your thinking during the day. You will catch yourself mid-reaction and question your impression before accepting it. You will remember, in the moment of frustration, that this person is acting from ignorance rather than malice. You will feel the pull of anxiety about the future and hear your own written words reminding you to focus on what you can control right now.

This is what the Stoics meant by philosophy as a way of life. Not a set of beliefs you hold in your head, but a set of practices you embody in your actions. And journaling — simple, private, consistent — is one of the most effective ways to bridge the gap between knowing and doing.

Pick up a notebook. Open it to the first page. And ask yourself the question Marcus asked every evening: what did I do today, and how can I do better tomorrow?
