If your to-do list feels like a never-ending scroll that leaves you exhausted by noon, the 1-3-5 rule might be the reset you need. Instead of dumping every task into one list, it gives each workday a clear shape: one big task, three medium tasks, and five small tasks. That’s nine in total, no more.
The built-in constraint is the point. Many productivity failures come not from laziness but from trying to do too much at once. Priorities blur, and by mid-afternoon you’ve been busy all day but finished nothing important. Capping the list at nine items, organized by effort, forces you to decide what matters before the day begins.
This guide walks through the method in five steps, with examples for two common remote roles. If you’ve tried time blocking or the Eisenhower matrix and want something lighter, this fits into your planning routine easily.
What Is the 1-3-5 Rule?
The 1-3-5 rule was popularized by Alex Cavoulacos, co-founder of The Muse, as an alternative to bloated task lists. Each morning, or the evening before, you plan your day around exactly nine tasks in three tiers:
- 1 big task: high-effort, high-impact work that needs sustained focus. If you finish it, the day feels worthwhile.
- 3 medium tasks: important but less demanding, such as follow-ups, short projects, and deliverables that don’t need peak concentration.
- 5 small tasks: quick items such as emails, approvals, and admin that keep things moving without draining you.
It works partly because it matches how energy tends to flow through a workday. You don’t have the same capacity at 9 a.m. as at 4 p.m. By assigning weight to tasks in advance, you stop making those decisions under pressure.
Quick Overview: The 5 Steps
| Step | Action | Time needed |
|---|---|---|
| 1 | Sort tasks into big, medium, and small | 5 minutes |
| 2 | Choose your one big task the night before | 2 minutes |
| 3 | Schedule three medium tasks around your big work | 3 minutes |
| 4 | Batch five small tasks in one block | 30 to 60 minutes total |
| 5 | Do a five-minute end-of-day reset | 5 minutes |
Why It Beats a Traditional To-Do List
A traditional list has no structure and no ceiling. You can add 30 tasks, mix urgent with trivial, and feel productive just by writing things down. Long lists also make it harder to decide what to do next, and that choice repeats all day.
The 1-3-5 rule makes those decisions once, before the day starts. Once work begins, you execute instead of choosing. It shares that principle with the Ivy Lee method, which also front-loads planning the night before. There’s a psychological payoff too. Nine well-chosen tasks give you a finish line that an endless list never does, and that clarity can be motivating.
5 Steps to Use the 1-3-5 Rule Every Day
1. Learn the Three Categories
A big task needs sustained, uninterrupted focus: writing a report, building a presentation, or finishing a complex deliverable. These often take two to four hours and use your best energy. Medium tasks are meaningful but manageable, such as a 45-minute review, a client call, an edit, or research that needs some concentration. Small tasks are the quick hits most people leave scattered across sticky notes and inboxes: replying to messages, approving a design, scheduling a meeting, or updating a tracker.
The most common mistake is mislabeling. If you call everything “medium” to avoid committing to a big task, you defeat the purpose. The method only works when you pick one hard thing and protect time for it.
2. Choose Your Big Task the Night Before
Deciding in the evening, while you still have perspective, keeps you from defaulting to reactive work first thing. Ask: if I could only finish one thing tomorrow, what would make the day a success? Be specific. “Work on the project” isn’t a big task, but “write the first draft of the Q3 strategy memo” is.
Then block two to three hours for it on your calendar, ideally in the morning if that’s when you concentrate best. Treat it like a meeting with your most important client. If you like a version with a shorter, more intense focus block, see our guide to the power hour.
3. Schedule Three Medium Tasks Around Your Big Work
Medium tasks usually fit in mid-morning and early afternoon, after the big block and before your energy dips. A rough guide is 30 to 90 minutes each. If a task takes longer, it may be a big task in disguise. Group similar ones together with the task batching method, for example all calls in one block, to cut context switching. Three is the limit for a reason: five or six medium tasks means none gets proper attention.
4. Batch Your Five Small Tasks
Small tasks are quicksand when they interrupt your focus. Replying to one message might take two minutes, but the interruption can cost much more in lost concentration, which we explain in our guide to attention residue. Batch all five into a dedicated block, often the last 45 to 60 minutes of the workday.
Move fast: set a timer and clear them in sequence. Because your important work is done, the low stakes feel like a reward. If a new small task arrives mid-morning, add it to the list instead of handling it right away.
5. Do a Five-Minute Reset Before You Stop
After the small tasks, review what you finished, note what’s incomplete, and draft tomorrow’s list, starting with the big task. Three questions help: Did I finish my big task, and if not does it carry over or get replaced? Which three medium tasks matter most tomorrow? Do any small tasks need to roll forward? The reset takes about as long as a quick scroll through your phone and makes the next morning much easier. It fits neatly into a work shutdown ritual.

These are made-up examples to show the structure. Swap in your own tasks.
| Content strategist | Project manager | |
|---|---|---|
| 1 big | Write the first full draft of a 2,000-word client report | Build the Q3 project roadmap |
| 3 medium | Respond to client feedback; attend a 45-minute team sync; update the project timeline | Run a 30-minute stakeholder check-in; draft a risk summary; review a contractor’s milestone |
| 5 small | Reply to three Slack threads; approve two mockups; book a meeting; forward an invoice; update a CRM contact | Answer five status requests; post the weekly update; update two task statuses; schedule sprint planning; confirm a vendor deadline |
When the Rule Doesn’t Fit
- Meeting-heavy days: shrink the big task to a 90-minute deliverable and count meetings that need preparation as medium tasks.
- On-call or support roles: your small tasks arrive constantly. Use a fixed “inbox hour” two or three times a day instead of one batch.
- You never finish the nine: that’s information. Shrink the big task to a day-sized deliverable, or cut the medium tier to two.
- You want a stricter system: try the Ivy Lee method, or use Parkinson’s Law deadlines to keep tasks from expanding.
Some books pair well with this method. Gary Keller’s The One Thing covers picking a single priority in depth; see our roundup of productivity books for remote workers.
Try It Tomorrow
Tonight, before you close your laptop, pick one big task, choose three medium tasks, and jot down five small items. That’s the whole setup, and it takes about five minutes. Give it a week, then adjust the numbers if your job needs it. The philosophy stays the same: do less, on purpose, and do it better.
Frequently Asked Questions
What is the 1-3-5 rule?
A daily planning framework that limits each workday to nine tasks: one big, three medium, and five small. It was popularized by Alex Cavoulacos of The Muse and aims to reduce list overload and give you a clearer finish line.
How is it different from a regular to-do list?
A regular list has no ceiling and no weighting. The 1-3-5 rule caps the list at nine and assigns each task an effort tier, so you prioritize once, before the day starts, instead of re-deciding all day.
Can I use it with meetings all day?
Yes. On meeting-heavy days, make the big task shorter, count meetings that need preparation or decisions as medium tasks, and keep the batching rule for small tasks.
What if I don’t finish all nine?
Incomplete tasks are data, not failure. If you regularly miss the big task, it may be too large. If small tasks pile up, you may be adding too many medium items. Over a week you’ll calibrate what fits in your day.
What tools work best?
Any tool: a notebook, a planner, Notion, Todoist, or a sticky note. A simple page with one line for the big task, three for medium, and five for small is enough. Our list of the best task management apps can help if you want a digital option.
