Most productivity systems fail for a boring reason. They need a perfect day to work. One surprise meeting and the whole plan collapses, along with your mood.
The 3-3-3 method is built to survive imperfect days. It asks you to plan very little: three blocks of three things. The writer Oliver Burkeman describes it as the method he uses himself.
Quick answer: The 3-3-3 rule is a daily plan with three parts: three hours of deep work on your most important project, three shorter tasks (urgent ones, or ones you’ve been avoiding), and three maintenance activities such as exercise, journaling or clearing your inbox. Burkeman says to change the numbers if they don’t fit.
What is the 3-3-3 rule?
Burkeman, author of Four Thousand Weeks, calls it the 3-3-3 method. The structure, as he outlines it:
- Three hours of deep work on your most important current project, with a specific goal for that day’s progress.
- Three shorter tasks, usually urgent to-dos or things you’ve been avoiding, each taking a few minutes. Calls and meetings count here.
- Three maintenance activities. He keeps this category deliberately broad: journaling, clearing the inbox, exercise.
He’s relaxed about the details. If you object that it won’t work for you, he suggests you “make up your own rule.” What matters, he says, is the underlying principles. He also says the method means he doesn’t start each day “on a tightrope,” needing everything to go exactly right (Inc.).
One honest caveat first: no study has tested the 3-3-3 method itself. It’s a framework one writer found useful, not a research-backed system. We include it because it’s simple, flexible and easy to try for a week.
What a 3-3-3 day could look like
This is an illustrative example, not a real person’s schedule. Say you’re a freelance writer with an article due Friday.
| Part | What goes in it |
|---|---|
| Three hours of deep work | Draft the middle section of the article. Goal for today: 1,200 words |
| Three shorter tasks | Reply to the editor about the deadline. Send the overdue invoice. Book the dentist (the one you’ve been avoiding for a month) |
| Three maintenance activities | A 30-minute walk. Clear the inbox to under 10 emails. Ten minutes of tidying the desk and planning tomorrow |
The three hours don’t have to be in one block. Two 90-minute sessions work, and so do three one-hour ones, as long as they’re on the same project.
Why it might work
We can’t prove it works, but there are sensible reasons why it could:
- It limits your day. A list of three things can be finished. A list of fifteen can’t.
- It protects the important work. The deep work block is named and given hours, so it doesn’t get squeezed out by small tasks.
- It gives small tasks a home. The “avoiding” tasks are in the plan instead of nagging you.
- It counts maintenance as part of the day. Exercise and an empty inbox aren’t treated as extras.
How to start using it
- Choose tomorrow’s deep work project tonight. Write the goal as an outcome: “finish the pricing section,” not “work on proposal.”
- List three short tasks. Pick one that you’ve been putting off.
- List three maintenance activities. Keep them small enough to actually happen.
- Block the three hours in your calendar. See our guides to time blocking vs time boxing and our deep work schedule template.
- Use a timer if you drift. The Pomodoro Technique works well inside a deep work block. See also how long a Pomodoro break should be.
Common mistakes
- Treating “three” as sacred. Burkeman himself says to change the numbers. If two hours is realistic on your meeting-heavy days, plan two.
- Putting five projects in the deep work slot. The deep work block is for one project.
- Counting email as deep work. Email belongs in the short tasks or maintenance.
- Skipping the planning step. Five minutes the night before is what makes the day work.
- Not knowing what’s important. If everything feels equally urgent, sort your tasks with the Eisenhower Matrix first.
Who it might not suit
If your job is mostly reacting to other people, such as support, on-call work or caring for small children, three protected hours may not exist. Scale it down: one hour of deep work, two short tasks, one maintenance activity. If you don’t know whether you can find the time, track a couple of weeks first; our time tracking guide covers how.
Frequently asked questions
Who created the 3-3-3 rule? Oliver Burkeman calls it the 3-3-3 method and says he uses it himself. The Inc. article we cite doesn’t credit anyone else with devising it.
Does the 3-3-3 method work? There’s no research on this specific method. It’s a flexible planning framework, and the sensible test is to try it for a week and see whether your most important work moves forward.
Do the three hours have to be in one block? No. Split them into shorter sessions if you like, as long as they go to the same important project.
Can I change the numbers? Yes. Burkeman encourages it, saying you should make up your own rule if the numbers don’t fit.
