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.
“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…”
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.
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.
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.
- 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
- 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
Watch the methodology work.
Three specimens from a single real session: the same situation, before and after, the full transcript, and the skill answering live in the channel where the work happens.
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.
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.
The same skill, where the work happens.
No new app to learn. The methodology runs over the WhatsApp Business API, so the answer lands as a reply in the thread you’re already in — same rigour, zero context-switch.
What it does, specifically.
Each capability is a distinct move drawn straight from the source methodology — not a generic assistant guessing.
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.
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.
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.
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.
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.
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.
Graded before it shipped.
Every skill is scored against independent scenarios for methodology fidelity before it goes live — not vibes, a rubric.
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.
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.
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.
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.
Grounded in the original work.
Every answer traces back to a real source and the practitioner who wrote it — not a secondhand summary. Here is the source of record.
