Marcus Aurelius spent twenty years as emperor of Rome. He commanded armies, adjudicated disputes, managed a bureaucracy of hundreds of thousands of people. He was one of the most powerful humans alive.
Every morning, he thought about death.
Not in a morbid way. Not in a paralyzed, terrified way. In a structured, deliberate way that he wrote about in a private journal he never intended anyone to read. We now call that journal Meditations.
I’ve been building life visualization tools for the past year. I’ve read a lot about mortality awareness — the psychology of it, the neuroscience, the philosophical traditions. But the Stoics, and Marcus Aurelius specifically, gave me something the modern literature mostly doesn’t: a practice. A daily structure for thinking about time that actually changes behavior.
Here’s what he did. And here’s what I built from it.
The Three Stoic Mortality Practices
Marcus Aurelius used three distinct practices in Meditations, all related to time and death. Most people who write about Stoicism collapse them into one vague idea (“memento mori”). They’re actually quite different.
Practice 1: Negative Visualization (Premeditatio Malorum)
Every morning, Marcus would spend a few minutes imagining that today might be his last day. Not dramatically — he did this matter-of-factly, almost as a calibration exercise.
The goal wasn’t to feel sad. The goal was to reset attention. When you genuinely believe you might not have tomorrow, the things you’ve been putting off start to feel different. The conversation you keep delaying with your son. The work you’ve been deferring.
From Meditations:
“You could leave life right now. Let that determine what you do and say and think.”
He wrote this to himself. He was the emperor. He still needed the reminder.
Practice 2: Temporal Zooming
Marcus practiced what I’d call temporal zooming — deliberately shifting between the very short-term and the very long-term perspective on any given moment.
He’d look at something that was stressing him out — a political crisis, a difficult person, a decision he had to make — and then zoom out: In 100 years, will anyone know this happened? In 1,000 years?
From Meditations:
“Think of yourself as dead. You have lived your life. Now take what’s left and live it properly.”
The zoom-out wasn’t pessimism. It was a way of identifying what actually mattered. If something would matter in 100 years, it was worth his full attention. If it wouldn’t, it deserved proportional attention — which usually meant less.
Practice 3: Role Stripping
The third practice is the strangest and most powerful. Marcus would periodically strip away his identity — emperor, general, father, son — and ask: What remains when you remove all the roles?
The answer he kept arriving at was: a small amount of time, directed by attention.
That’s it. Strip away everything. What you have left is the time you’re choosing to pay attention to, right now.
This practice was directly connected to his mortality awareness. He wrote about figures from Roman history — people who had been famous, powerful, feared — and noted that they were completely forgotten. The empire had forgotten them. History had forgotten them.
From Meditations:
“Alexander the Great and his mule driver both died and the same thing happened to both.”
What I Took From This
When I started building life visualization tools, I was mostly interested in the data side. How many weeks do you have? What percentage have you used? How does your trajectory compare to historical figures?
The Stoic framework added something the data couldn’t: a daily practice for engaging with that data.
The 900-square life grid I built is useful for seeing your life once. But Marcus Aurelius didn’t look at his situation once and then move on. He came back to it every morning. He made mortality awareness a habit, not an insight.
That’s a different thing.
I added a feature to my life grid tool based on this: a daily prompt mode. Instead of just showing you the grid, it asks you three questions:
1. The negative visualization question: If today were your last day, what would you do differently? 2. The zoom question: What are you focused on right now? Will it matter in 10 years? 3. The stripping question: Set aside your roles. What do you actually want to do with the time you have?
These aren’t my questions. They’re Marcus Aurelius’s questions, slightly translated.
The Pattern I Found in His Journals
I mapped Marcus Aurelius’s life as part of the 74-figure historical project. What struck me about his life, on the grid, was how much of it was spent in circumstances he hadn’t chosen.
He hadn’t wanted to be emperor. He wanted to be a philosopher. He spent decades in wars he didn’t start, administering an empire he inherited, dealing with a political situation that was largely beyond his control.
And yet, Meditations — which he wrote during military campaigns, often in a tent — contains some of the most calm, clear-eyed writing in human history.
The mortality practice wasn’t separate from his busy life. It was how he survived the busy life with his attention intact.
The Modern Problem
The reason I keep coming back to Marcus Aurelius is that the modern version of the mortality problem is different from what he faced.
He lived in a world where death was visible — plague, warfare, infant mortality rates. He didn’t need reminders that life was finite. The reminder was everywhere.
We live in a world that actively hides mortality. We don’t see death. We see Netflix queues and social media feeds and productivity systems. The finitude of life has been very effectively obscured.
So his practices need to be imported deliberately. You have to choose to look at the grid. You have to choose to ask the zoom question. You have to choose to strip away the roles.
That’s why I built tools for it instead of just reading about it.
The Practice, Distilled
Marcus Aurelius’s actual daily practice, adapted for now:
- Morning: Spend 2 minutes with the question: If today were my last, what would I regret not doing? Act on one answer.
- Midday: When stressed or distracted, ask: Will this matter in 10 years? Allocate attention accordingly.
- Evening: Strip the roles. Not the job title, the parent role, the friend role. Just: What did I actually choose to pay attention to today? Was that right?
The tools I’ve built are scaffolding for this practice. The 900-square grid makes the question of time visible. The historical comparison shows what others chose to pay attention to. The life density score asks you to evaluate whether the attention has been well-placed.
But the practice is older than any of the tools.
Marcus Aurelius did it in a tent in 170 AD, knowing he might not make it back to Rome.
The fundamentals haven’t changed.
