What Is the Dichotomy of Control? How to Practice It Daily

The dichotomy of control is the Stoic idea that some things are up to you and some things are not, and that your peace and performance depend on knowing the difference. What’s up to you is your own judgments, choices, effort and responses; what isn’t is the outcome, other people, the market, your reputation and the past. You practice it by sorting every worry into those two columns, putting all your energy into the first one and deliberately letting go of the second.

I’ve seen this play out with more founders than I can count, and on myself while building Addicted2Success. The people who burn out aren’t usually the ones working the hardest. They’re the ones spending most of their energy on things they were never in charge of: the investor who hasn’t replied, the competitor’s launch, the one-star review, the algorithm change. The dichotomy of control is the simplest fix I know for that leak, and it’s about 2,000 years old.

Before we get practical, here’s Ryan Holiday from Daily Stoic putting the whole idea into under two minutes. Watch it once, then we’ll turn it into something you can use on a Monday morning.

What Is the Dichotomy of Control?

The idea comes from Epictetus, a Greek Stoic teacher who was born a slave and went on to become one of the most influential teachers of the Roman era. The very first line of his handbook, the Enchiridion, says it plainly: “Some things are in our control and others not. Things in our control are opinion, pursuit, desire, aversion, and, in a word, whatever are our own actions. Things not in our control are body, property, reputation, command, and, in one word, whatever are not our own actions.”

That’s the whole framework. Two buckets. Epictetus wasn’t saying the second bucket doesn’t matter. He was saying it isn’t yours to command, so tying your peace of mind to it is a bad trade. He also warned what happens when you get it wrong: you’ll lament, you’ll be disturbed, and you’ll find fault with everyone around you. If you’ve ever spent a Sunday night refreshing a dashboard, you know exactly what he meant.

Here’s the line I want you to remember: you don’t control the outcome, you control the input, and the input is where all your power lives.

Up to Me vs. Not Up to Me: A Founder’s Version

The ancient examples are about property, reputation and office. Swap in the modern equivalents and it gets very real, very fast. This is the table I’d put on the wall of any small team:

Notice something about the left column. Every item is an action you can take today. Every item on the right is a result you can only influence. That’s not an accident. The dichotomy of control is really a tool for moving your attention from results back to actions.

Why It Works (and Why It’s Not Just a Nice Quote)

Most people treat this as a calming thought. It’s actually a performance tool. When your attention is stuck on what you can’t control, you’re spending energy without producing anything. Worry feels like work, but it ships nothing.

There’s also some modern evidence behind it. Writing in Psychology Today, Stoic author and therapist Tim LeBon reported that during Stoic Week 2022, more than 2,000 participants rated how much they “control the controllables” and “let go of things I can’t control.” Both habits correlated positively with well-being, and controlling the controllables showed a strong link to flourishing. It’s survey data, not a clinical trial, but it lines up with what I’ve watched happen to people who adopt the habit.

I keep a few Stoic quotes on my phone for the days the noise gets loud, but a quote only helps if you’ve already done the sorting. The sorting is the practice.

How to Practice the Dichotomy of Control: 6 Steps

This isn’t a philosophy lecture. Here’s exactly what I’d do if you want to use this starting tomorrow.

1. Do a two-column brain dump. Take a notebook, draw a line down the middle and write “Up to me” and “Not up to me” at the top. List everything that’s bothering you right now. Don’t judge it, just sort it. Most people find the right column is twice as long as the left, and that alone is a wake-up call.
2. Turn every outcome into an input. For each item on the right, ask, “What part of this is mine?” “Will the investor say yes?” becomes “Send three more warm intros this week and tighten slide four.” You’re not ignoring the outcome. You’re finding the handle on it.
3. Set process goals, not just outcome goals. Keep the big target, but judge your day on the part you own. “Hit $50K MRR” is a direction. “Ten sales conversations this week” is a scoreboard you control.
4. Pre-decide your response. Bad news is coming at some point. Decide now what you’ll do when the deal falls through or the launch flops: take a walk, write down what you can learn, make the next call within 24 hours. A response you’ve already chosen is a response that’s up to you.
5. Name it out loud in the moment. When you feel the spiral start, say, “That’s not up to me.” It sounds simple. It interrupts the loop long enough for you to ask the better question: what is?
6. Review it at night. The Stoics loved an evening review. Ask three questions: Where did I spend energy on things I couldn’t control? Where did I let something I could control slide? What will I own tomorrow?

The Daily Dichotomy Checklist

• Morning: write the one result I want today and the three actions that are fully mine.
• Before any hard conversation: list what I’ll say and how I’ll act, not how they’ll react.
• When I check metrics: note one input I’ll change, then close the tab.
• When something goes wrong: “Not up to me” first, then “What’s my next move?”
• Evening: three-question review, two minutes, done.

Dichotomy of Control vs. Locus of Control

These two get mixed up all the time, so let’s clear it up. If you’ve read about building an internal locus of control, this will sound familiar, but they aren’t the same thing.

Locus of control is a psychology concept about what you believe drives your life. People with an internal locus believe their actions shape their results. People with an external locus believe luck, other people or circumstances run the show. The dichotomy of control is a practice for sorting each specific situation into what’s actually yours and what isn’t.

Here’s how I’d put them together. Locus of control is the belief that your effort matters. The dichotomy of control is the discipline to aim that effort only where it can land. An internal locus without the dichotomy can turn into control-freak behavior and self-blame for things you never owned. The dichotomy without an internal locus can turn into passive acceptance. Together, you get someone who takes full ownership of their actions and stays calm about the rest.

What About Things You Can Partly Control?

Most of business lives in a gray zone. You can’t control whether a client signs, but you’re not powerless either. Philosopher William Irvine, in A Guide to the Good Life, suggested a “trichotomy of control”: things you control completely, things you don’t control at all, and things you control partly.

It’s a useful nuance, but don’t let it become a loophole. The trick for anything in the middle is the same as step two above: break it down until you find the piece that’s entirely yours, then make that your goal. Irvine’s own example is a tennis match. You can’t control whether you win, but you can set the goal of playing your best. That’s the dichotomy doing its job inside the gray zone.

Common Mistakes When People Try This

Using it as an excuse. “Revenue isn’t up to me” is true and useless if you stop there. The dichotomy should make you more active, not less. The left column is supposed to be crowded with action.

Pretending not to care. Letting go of the outcome isn’t the same as not wanting it. You can want the deal badly and still refuse to let your peace of mind ride on it.

Putting other people in the wrong column. You don’t control your co-founder, your kids or your customers. You control how clearly you communicate, what boundaries you set and how you show up. That’s still a lot of power. It’s just the right kind.

Doing it once. One brain dump feels great. The benefit comes from doing the sorting every single day until it’s automatic.

The Bottom Line

Every founder I respect has some version of this habit, whether they call it Stoicism or not. They work like crazy on the things that are theirs, and they refuse to bleed energy on everything else. That’s not detachment. That’s focus.

So grab a notebook tonight and draw the line down the middle. Put what’s bothering you in the right column, find the action hiding inside each one, and move it to the left. Then go do the left column. That’s the dichotomy of control, and it’s one of the most practical things you’ll ever learn.

Frequently Asked Questions

What is the dichotomy of control in simple terms?

It’s the Stoic idea that some things are up to you, like your choices, effort and responses, and some aren’t, like outcomes, other people and the past. Focus your energy on the first group and let go of the second.

Who came up with the dichotomy of control?

The Stoic philosopher Epictetus, who taught in the first and second centuries AD. It opens his Enchiridion, or Handbook, and later shaped Marcus Aurelius’s thinking and modern cognitive behavioral therapy.

How do you practice the dichotomy of control every day?

Write a two-column list of what’s up to you and what isn’t, turn each outcome into an action you own, set process goals, pre-decide your response to setbacks and review at night where your energy went.

What is the difference between the dichotomy of control and locus of control?

Locus of control is a belief about whether your actions shape your results. The dichotomy of control is a practice for sorting each situation into what’s yours and what isn’t. The first fuels ownership; the second aims it.

Does the dichotomy of control mean you should stop caring about results?

No. You can want a result and work hard for it. The point is to judge yourself on the inputs you own and stop letting your peace of mind depend on outcomes you can only influence.
