Zen to Done (ZTD)

Simplicity boils down to two steps: Identify the essential. Eliminate the rest.

Zen to Done is a minimalist productivity system built around 10 habits adopted sequentially, one per month. Instead of overhauling your entire workflow at once, ZTD installs one focused behavior at a time — starting with ubiquitous capture and daily Most Important Tasks — until the system runs automatically. Designed by Leo Babauta as a simpler, habit-grounded alternative to GTD, it is the productivity framework for people who have tried complex systems and abandoned them.

The gap

Do the three tasks that matter most — build the rest one habit at a time

ZTD structures productivity as 10 discrete habits implemented one per month: Collect, Process, Plan, Do, Simple Trusted System, Organize, Review, Simplify, Routine, and Find Your Passion. The keystone daily habit is the MIT ritual — every morning, before reactive work begins, the user writes 1-3 Most Important Tasks whose completion defines a successful day. Weekly, the user sets 3-4 Big Rocks, the most important outcomes for the coming week. Inboxes are processed once or twice daily using a strict four-path decision tree: delete, delegate, defer, or do immediately (2-minute rule). The entire system is designed for the simplest possible tools — paper, plain text, minimal context lists like @home, @work, @errands — so that habits, not tools, carry the productivity load. ZTD diverges from GTD in three deliberate ways: it prioritizes via MITs rather than treating all next actions equally, it treats habit formation as the core design problem, and it champions radical simplicity as a first-class outcome.

The problem

Most productivity systems fail at implementation, not design. People read GTD, build an elaborate system, and abandon it within weeks because they tried to change everything at once. Meanwhile, reactive work — email, meetings, Slack — expands to fill the day, leaving the most important work perpetually deferred. ZTD addresses the habit-formation gap directly: no system, however well designed, works until its behaviors become automatic, and no behavior becomes automatic when you try to install ten at once.

The solution

Walk away from every session with a concrete daily MIT list and a clear next habit to build — not another system to design, but one specific behavior to practice until it runs without effort.

You bring
  • Your current task backlog, open loops, or inbox items to process
  • A sense of which areas of life or work feel most chaotic or neglected
  • Your existing daily schedule or routine, even a broken one
  • Honest description of which past productivity systems you have tried and abandoned
You get
  • A written daily MIT list — 1-3 specific tasks named and ready to execute before reactive work begins
  • A weekly Big Rocks plan — 3-4 priority outcomes with protected time blocks
  • A personalized ZTD habit adoption sequence — which of the 10 habits to build first, given your specific pain points
  • A morning, evening, and weekly routine template designed around your actual schedule

Without the skill

You start the day with 60 unread emails, 3 Slack threads, and a task list with 40 items, all marked important. By 11am you have responded to emails and attended a standup but have not touched the Henderson proposal — the thing that actually matters. You feel busy but not productive, and the most important work keeps rolling to tomorrow.

Specimen BAfter
With Zen to Done (ZTD)

You write your two MITs before opening email: Henderson proposal and Q2 headcount response. You spend 20 minutes processing your inbox to zero using the four-decision rule. By 10am both MITs are done. The rest of the day is clear for reactive work. Nothing slipped. Next month you add the weekly Big Rocks habit — your most important projects will advance every week, not only when they become crises.

Let's find your Most Important Tasks for today — before we look at anything in your inbox or task list. If today ended and you felt genuinely productive, what one or two things would have to be done? Don't filter yet, just name them.
Honestly? I need to finish the draft proposal for the Henderson account and respond to my manager's question about Q2 headcount. But I also have like 60 unread emails and three Slack threads I've been ignoring.
Good — those two are your MITs for today: the Henderson proposal draft and the Q2 headcount response. Write them down right now, physically or in a note, before we touch anything else. The 60 emails and Slack threads exist, but they don't get to decide your day before you do. That's the MIT rule: written, committed, done before reactive work begins. Once your MITs are locked, we can do an Inbox Decision Sprint — I'll walk you through the delete-delegate-defer-do decision on each item so you process to zero without losing anything. Want to write the MITs first and then clear the backlog?
Yeah, I wrote them down. The inbox thing sounds useful — I usually just stare at it and close the tab.
That staring-and-closing is what ZTD calls an unprocessed inbox — every item in there is an open loop taking up mental RAM. We close each loop with one decision: delete (not actionable, not needed), delegate (someone else should own this), defer (you'll do it, but not today — goes on a list with a date), or do it now if it takes under two minutes. Give me the first five items — subject line and sender is enough — and we'll run them through.
Newsletter from SaaS Weekly, finance asking me to confirm my expense report, a calendar invite for a standup I already declined, a question from a junior colleague about a process doc, and a vendor pitch from someone I've never heard of.
Fast decisions: Newsletter — delete, or archive if you actually read it. Expense confirmation — do it now, that is a 90-second task and it clears a commitment. Calendar invite you already declined — delete, it is resolved. Junior colleague's process question — if you can answer in under two minutes, do it now; if it needs a real answer, defer it: add 'respond to [name] re: process doc' to your task list with a date. Vendor pitch — delete. Five items, four closed permanently. This is exactly ZTD's Process habit — you are not managing your inbox, you are emptying it. How many are left?
A lot, but this actually feels doable now. I thought this would take an hour.
Most people discover their inbox is 80% deletable once they stop treating every item as a potential commitment. Keep going with the same four decisions — delete, delegate, defer, do. When we are done, I want to look at where you are in the 10 ZTD habits and map out which one to build next. You already have the instinct for MITs. That is Habit 3. There are nine more, and we only tackle one per month.

Capabilities

What it does, specifically.

Each capability is a distinct move drawn straight from the source methodology — not a generic assistant guessing.

CapabilityC-01

Daily MIT Generator

Given your task backlog, current projects, or just the context of your day, this capability identifies and writes out your 1-3 Most Important Tasks — the specific items whose completion makes today a success regardless of what else happens. MITs are always selected before any reactive work begins.

Based on Babauta's Plan habit (ZTD Habit 3): each morning, before email or reactive tasks, the user commits in writing to 1-3 tasks of highest importance — distinguishing the vital few from the noisy many on the full task list.
CapabilityC-02

Weekly Big Rocks Planner

At the start of each week, this capability helps identify your 3-4 Big Rocks — the most important outcomes for the coming week — and block time to protect them before the calendar fills with lower-priority work. Outputs a written weekly plan you can reference each morning when setting MITs.

Based on ZTD's weekly planning practice where Big Rocks are named and scheduled first; Babauta frames this as the weekly counterpart to daily MITs, ensuring important projects advance every week rather than only when they become crises.
CapabilityC-03

Inbox Decision Sprint

Walk through a backlog of captured items — emails, notes, task lists — and apply ZTD's four-path decision tree to each one: delete, delegate, defer with a date, or do immediately if under two minutes. Reduces cognitive overhead by closing every open loop with a single clear decision.

Based on ZTD Habit 2 (Process): Babauta specifies processing all inboxes to zero once or twice daily using the same four-decision sequence, explicitly simplified from Allen's GTD processing workflow to remove ambiguity.
CapabilityC-04

ZTD Routine Architect

Designs a personalized morning routine, evening shutdown routine, and weekly review ritual based on your actual schedule, existing constraints, and which ZTD habits you have already built. The output is a repeatable routine template with specific times and trigger points — not a list of aspirational behaviors.

Based on ZTD Habit 9 (Routine): Babauta prescribes daily morning, evening, and weekly routines as the mechanism that makes the rest of ZTD automatic — habits embedded in routines require less willpower than habits requiring conscious daily activation.
CapabilityC-05

Weekly Review Facilitation

Guides you through the full ZTD weekly review: emptying all inboxes, reviewing every active project and context list, updating deferred tasks, and setting next week's Big Rocks. Ends with a trusted system that reflects current reality — nothing forgotten, nothing stale.

Based on ZTD Habit 7 (Review): Babauta specifies a structured weekly pass through all lists and projects before the new week begins, ensuring the system stays current and that Big Rocks are set while the week is still blank.
CapabilityC-06

Habit Adoption Roadmap

Assesses your current productivity pain points and recommends a month-by-month sequence for adopting ZTD's 10 habits, starting with the one that delivers the most immediate relief. Prevents the most common failure mode: attempting to install all 10 habits simultaneously.

Core to ZTD's design philosophy: Babauta explicitly structures the system as sequential monthly habit adoption, not a simultaneous overhaul — the roadmap operationalizes this sequencing for each user's specific situation and pain points.

What it produces
OutputD-01

Daily MIT Card

A focused written record of today's 1-3 Most Important Tasks, selected before reactive work begins — names each MIT specifically, notes why it is most important today, and fits on a single index card or note.

OutputD-02

Weekly Big Rocks Plan

A one-page weekly plan naming the 3-4 outcomes that must happen this week, with protected time blocks for each and a short rationale connecting each to longer-term goals.

OutputD-03

ZTD Habit Adoption Map

A personalized month-by-month roadmap showing which of the 10 ZTD habits to build in which order, based on your current pain points — includes the specific daily practice for each habit and a definition of success for each step.

OutputD-04

Inbox Processing Log

A processed list of captured inbox items, each routed through the delete-delegate-defer-do decision tree — leaves nothing unresolved and transforms a vague backlog into a set of clean, actionable next steps.

At launchI have tried GTD twice and abandoned it both times. I have a massive task list, no idea what to work on first, and I spend most of my day reacting to email. Can we figure out my Most Important Tasks for today and map out which ZTD habit I should build first?
