Most advice for overthinking points you at the thoughts themselves. Journal them. Replace the negative ones with positive ones. Breathe. Meditate. Run. But what if the thoughts were never the problem? Epictetus taught that it is not events that disturb us, but our judgements about them. Overthinking is not a volume problem. It is a judgement problem — somewhere in the loop you added a meaning to something that was otherwise neutral, and that meaning is what keeps you awake.

The Stoic diagnosis
The Stoics called the raw first take an impression — phantasia. An impression arrives (the look, the email, the traffic), and then you are asked whether to assent to it: to endorse the storyline it carries. The untrained mind assents instantly — "they disrespected me, because it felt that way." The trained mind withholds: I couldn't bet the house on that. As Marcus Aurelius put it, if you are distressed by anything external, the pain is not due to the thing itself but to your estimate of it.
Three moves to catch the judgement
1. Strip back to the first impression. Ask: what actually happened? Not your judgement, not the storyline — the event, in neutral terms. Keep asking. You'll usually find that not much happened, and it was small.
2. Filter the thought through the dichotomy of control. Thoughts arrive uninvited — that part is not up to you. What you do with them is. Ask: what part of this thought is up to me right now? Often the thought is demanding something literally impossible — changing the past, predicting the future, controlling other people. Overthinking is often a substitute for action; this question puts you back in the driver's seat.
3. The rational observer. The Stoics contemplated role models — what would Socrates do? You don't need to go that far: what would the calmest, wisest version of you think, say, or do in response to this event? Is checking your phone for the ninth time what that person would do?
The one-line practice, usable today: what actually happened, and what am I adding to it?
This builds on the dichotomy of control, and pairs with The Anxiety Trap: Why Fighting Makes It Worse from the same month.

Okay, have you ever had this experience? You're lying awake in bed, replaying a conversation that you had. Something that didn't go so well. Maybe you're replaying what you should have said or shouldn't have said, and it's keeping you awake. You can't let it go. You're ruminating and going over and over and over in your mind. And then you go beyond just thinking about this conversation. You're now thinking about what it means about you personally, about your life, about everything in your world.
The crazy thing about these thought loops, this type of overthinking: nobody talks about the thought itself. It's often not that serious. It could be a look that someone gave you, something that was implied, something that wasn't said, maybe an email. But the meaning that we give it makes it snowball, makes it pick up its own sort of gravity. Your mind took this thought and went wild with it. And that's something people don't address when it comes to overthinking. Overthinking is not a deep analysis. It's not a neutral report. It's a loop. It's often something small that just gets bigger and bigger, loops more and more, gets more meaningful every time it loops around.
My goal here is to give you a Stoic diagnosis of overthinking and to give you practical tools that you can start using today. It's probably going to contain advice that you've never heard before if you're quite new to Stoicism. Most of the common advice when it comes to dealing with overthinking has you look at the thoughts themselves. You're having too many thoughts. You're having the wrong thoughts. So let's journal about it. Let's unpack it, dissect it. Maybe we can replace the negative thought with a positive one. We can breathe, we can run, we can meditate. They're focused a lot on the thoughts — the content of the thought. Where the Stoic view is: what if the thoughts themselves aren't the problem? Maybe the thoughts themselves are neutral. Maybe it's more to do with what we are doing to the thoughts that causes the issue. It sounds kind of radical, but what if overthinking is not even a thinking problem?
Epictetus was a first-century Roman Stoic philosopher. He was originally a slave, and then he earned his freedom and taught, usually outside, to whoever would listen. In the end he had some pretty influential students, and he's widely regarded as one of the greatest Stoic thinkers of all time. And Epictetus had this idea that he kept coming back to. You may have heard it before — it's been borrowed and rehashed many times in popular self-improvement — but I'll say it again. It is not events that disturb us, but our judgements about the events.
Say you're stuck in traffic. The traffic isn't the problem, as tempting as it is to believe that it is. It's the thoughts that we are going to be late, and what that means, and what we're going to miss, and what this will mean for our reputation. The meaning that we give to the event is what disturbs us. The Stoic diagnosis isn't trying to get you to think better thoughts. It's trying to get you to notice when you add a judgement to what is otherwise a neutral event. It is that judgement that causes the disturbance and the suffering. And if we don't notice the judgement, then we're just going to assume that the event itself — reality itself — is inherently bad, and we are a victim of this bad circumstance.
The Stoics had this word, phantasia, which means impression. We're always getting these impressions as we go through life — knee-jerk reactions, the first storyline that pops into our head about a situation. And then we are asked: do we assent, not assent, or withhold assent — which means agreement — to this impression? To give assent means to endorse it. So if someone looks at you in a strange way, a Stoic would ask: do you assent to the impression that they disrespected you? A seasoned Stoic would say, I can't bet the house on that, because I don't really know. I couldn't say with a hundred percent certainty that they looked at me that way because they disrespected me. So I'm going to withhold assent. The untrained mind says: no, they disrespected me, because I felt that was the case. They give assent — they endorse, they agree, they fully believe the impression that first hits them.
Marcus Aurelius had a great line: if you are distressed by anything external, the pain is not due to the thing itself, but your estimate of it. He's paraphrasing Epictetus here, but I like that word — the estimate of it, not the thing.
So coming back to overthinking: it's not a thinking problem. The Stoics would say the reason you're lying awake, ruminating several layers deep, is because somewhere along the line you added a judgement. And your job isn't to stop thinking, isn't to replace the negative thoughts with positive thoughts, but to locate the judgement. What was the first judgement you added to this event? And more importantly: when I examine this judgement, does it hold up?
The first practical exercise is really simple: find the first impression. Ask the simple question, what actually happened? In a lot of CBT exercises, right at the top, before you do anything else, they'll say: describe the event in neutral terms. Not your judgement, not the storyline — what actually happened. And when you've located that, ask yourself again: okay, but what really happened here? What was my initial impression? As you ask, you'll find your mind still wants to interpret and add judgements. Just keep going. What actually happened? This is not to dismiss how you're feeling — it's to find the actual event, before we added any judgements. To our surprise, we'll often find that not much happened. It's usually pretty small.
The second exercise is to filter the thoughts through the dichotomy of control. Most of us are familiar with it: the world divides into things that are completely up to us and things that are not. The weather is not up to us; how we respond to the weather is. But it can also be applied to thoughts. Some thoughts just come to us. They sneak up in the middle of the night. Minds are not blank — they're thinking machines. So when a thought comes, ask: is this thought up to me? Usually it's not. It just comes. But what you do with the thought is up to you. When a heavy, difficult thought arrives, ask: what part of this is up to me right now? Sometimes the answer is nothing. Sometimes it's one or two things. It can be quite liberating to see that a thought is asking you to do something literally impossible — change the past, predict the future, control other people. You can say to that thought: you're asking me to do something that is not up to me. End of the road. But sometimes you do have an opportunity — to send a message, to put right a wrong. The overthinking loop is often a substitute for taking action, and that's why the dichotomy of control is useful here: it takes you out of the abstract chain of rumination, puts you back in the driver's seat, and asks where you're going to spend your effort now.
The third exercise is the rational observer. The Stoics often contemplated role models — what would Socrates do in this situation? Or they contemplated the sage, the ultimate wise person. I don't think we need to go that far. Just ask: what would a very calm and rational person do in this situation? How would they process this event? To make it tangible, think back to a time when you meditated, did yoga, went for a long run — something that made your body feel grounded and calm. Imagine what that version of you would think, say, or do in response to this event. It creates a nice bit of separation between you and the overthinking. The question isn't whether you suddenly feel good about the thoughts. It's: do I check my phone for the ninth time? Do I catastrophise? Is that what the wisest, calmest version of me would do? We usually know the answer, and it gives us a push out of the loop.
So those are the three Stoic moves. Strip back the impression — go back to the original event and keep asking what happened. Ask what is within my power here, using the dichotomy of control. And the rational observer — what would a role model, or the wisest version of myself, do. You don't need all three every time. Sometimes one is enough. The idea is that we stop treating overthinking as a thinking problem, and realise it's the subtle judgements we're adding that cause the suffering. These tools get you out of the loop — they give you something concrete to do the next time you're stuck in a spiral.
If you want one simple practice to start today, even when you're not in a loop: ask, what has actually happened, and what am I adding to it? Journal on it, think it through, meditate on it. If you get good at answering that — here's what happened, and here's what I added — it becomes an automatic skill, and you'll be shocked. Overthinking happens far less, and you'll have a much clearer head to deal with situations as they come.
