Getting Things Done (GTD) is a personal productivity method developed by David Allen that helps you capture every task, idea, and commitment, decide what each one means, and put it where it belongs — so your mind is free to focus on doing the work, not remembering it. This page is a complete walkthrough of the GTD method.

What Is the GTD Method?
GTD — short for Getting Things Done — is a productivity system created by productivity consultant David Allen and introduced in his 2001 book Getting Things Done: The Art of Stress-Free Productivity. The book has sold millions of copies worldwide and has shaped how productivity is taught for over two decades.
Allen’s central insight is that your mind is for having ideas, not holding them. When tasks live in your head, they create background noise that drains focus and energy. When they live in a trusted external system — and you process them through a clear workflow — your mind is free to do the actual work.
The result Allen calls “stress-free productivity” — a state of being appropriately engaged with whatever you’re doing right now, instead of distracted by everything else competing for attention.
Why GTD Works
GTD works because it solves three problems at once:
- Mental clutter. Every unfinished thought, half-remembered task, and “I should…” reminder takes up bandwidth. Externalizing them frees the mind.
- Decision fatigue. Most of the energy spent on tasks goes to deciding what to do, not doing them. GTD pushes those decisions to a single weekly review so they don’t recur all week long.
- Trust. Once you trust your system to remember everything, your mind stops trying to remember on its own — and that’s when real focus becomes possible.
Allen calls the unfinished items in your head “open loops.” GTD is, more than anything else, a method for closing them.
The Five Stages of the GTD Workflow
GTD organizes everything you do through a five-stage workflow:
- Capture every input — tasks, ideas, commitments, paperwork — into trusted external collection tools.
- Clarify what each item means and what action (if any) it requires.
- Organize the results into the right lists: projects, next actions, calendar, waiting for, someday/maybe, and reference.
- Reflect on the system regularly so you continue to trust it. The weekly review is the heartbeat of GTD.
- Engage with confidence, choosing the right thing to work on right now.
The next sections cover each stage in detail.
Step 1: Capture
The first stage is to collect everything that has your attention into a small number of trusted “in-trays” — places outside your head where every input goes to wait for processing. This includes physical paper, digital messages, ideas, decisions you’ve been avoiding, projects you haven’t started, things you’ve borrowed and need to return — anything that isn’t where it should be or in the state it should be in.
Capturing has two parts: a physical sweep of your environment, and a mental sweep of your head.
Physical Gathering
Walk through your home and workspace and collect anything that requires action or doesn’t belong where it is. Allen suggests working through:
- Your desk and desk drawers
- Countertops, shelves, and walls
- Inside cabinets and on the floor
- Bulletin boards and inboxes
- Equipment that’s broken, outdated, or out of place
Four categories of items can stay where they are without being captured: supplies (things you regularly use), reference material (books, manuals, files), decoration (photos, plants, artwork), and equipment (computer, phone, printer). Everything else goes in the in-tray.
If something is too big to fit physically — a broken printer, an awkward piece of furniture, a whole room that needs sorting — write a note representing it and drop the note in the in-tray instead.
Mental Gathering: The Mind Sweep
Once your environment is clear, do the same for your mind. Sit down with a blank list and write down every thought, idea, project, or open loop currently competing for your attention. Allen calls this a mind sweep, and the first one typically uncovers far more than people expect — old commitments, half-formed plans, conversations you meant to have, books you wanted to read, things you wanted to fix.
Use our free Mind Sweep template to capture each one.
Categories that prompt useful mind sweep entries:
- Projects started but not completed
- Projects you’ve been meaning to start
- Commitments to other people
- Phone calls and messages
- Errands and shopping lists
- Things to clean, fix, or organize
- Health, finance, and household items
- Career and personal development goals
A thorough first capture takes most people one to six hours. It feels like work — but the moment you finish, the relief is immediate. Everything that was pulling at you is now waiting on paper, where you can deal with it deliberately instead of accidentally.
Step 2: Clarify
The capture stage is deliberately mindless — you’re gathering, not deciding. Clarification is where you actually think about each item.
For every single thing in your in-tray, ask one question: is it actionable?
If It’s Not Actionable
Three options:
- Trash it if you don’t need it now and won’t need it later.
- Incubate it on a Someday / Maybe list if it’s an idea you might want to revisit one day, or in a tickler file if you want it to resurface on a specific future date.
- File it as reference if it’s information you’ll want later — manuals, account numbers, articles, contact details.
If It Is Actionable
Ask: what’s the desired outcome, and what’s the very next physical action?
- If the outcome takes more than one step, it’s a project — capture it on your projects list and identify the next concrete action.
- If the next action takes less than two minutes, do it immediately. The cost of capturing it, scheduling it, and revisiting it later is greater than the cost of doing it on the spot. This is the famous “two-minute rule.”
- If it takes longer than two minutes and someone else is the right person, delegate and track it on your Waiting For list.
- If it takes longer than two minutes and you’re the right person, defer it — to a specific time on your calendar, or to your Next Actions list.
For a visual version of this decision process, see our interactive GTD flowchart.
Step 3: Organize
Once you’ve clarified each item, it goes into the right list. GTD uses six core lists, and that’s it — anything more is overhead. Free printables for each one are on our GTD planner page.
The Projects List
In GTD, a project is any outcome that requires more than one action to complete — “plan a birthday party,” “renovate the bathroom,” “launch the website.” Every project on the list must have at least one concrete next action defined. Use our free Projects List template to track them. The projects list is reviewed weekly to make sure nothing has stalled.
The Next Actions List
This is where every actionable, deferred, single-step task lives — things that take longer than two minutes and aren’t tied to a specific date. Use our free Next Actions list template.
If your next actions list grows long, sort it by context — the place, tool, or condition you need to actually do the task. Common contexts include calls, errands, computer, office, home, and waiting room. When you’re at your desk, you scan the “computer” list. When you’re in the car, you scan “errands.” Context-sorting means the right tasks always rise to the top.
The Calendar
The GTD calendar is sacred. Only put items there that must happen on a specific date or at a specific time:
- Time-specific actions (a 2 p.m. dentist appointment)
- Day-specific actions (a phone call that has to happen Tuesday)
- Day-specific information (documents to bring to a Friday meeting)
Everything else goes on the next actions list. Use our free GTD Calendar template to keep it clean.
The Waiting For List
Anything you’ve delegated, requested, or are otherwise expecting from someone else lives here. Reviewed weekly so nothing slips. Use our free Waiting For list template — it’s organized by person, so when you talk to someone you can see everything you’re waiting on at once.
The Someday / Maybe List
Ideas, possibilities, and goals you’re not committing to right now but don’t want to lose: trips you’d like to take, skills you’d like to learn, businesses you’d like to start. Use our free Someday / Maybe list.
Reviewed weekly or monthly — items that catch your attention can be promoted into active projects; items that no longer interest you get deleted.
Reference Material
Not a list, but a system. Information you may need later — articles, account numbers, manuals, receipts — gets filed somewhere you can find it again in under a minute. A simple A–Z filing system, paper or digital, handles most of it. The discipline is making it fast: if filing takes more than a minute, you’ll stop doing it.

Step 4: Reflect
Capturing and organizing only work if you trust the system. The system only stays trustworthy if you review it. Reflection — especially the weekly review — is what makes the difference between GTD that works and GTD that fades after two weeks.
The Daily Review
A short daily check of your calendar and next actions list to see what your day actually contains and what you can fit in around it.
The Weekly Review
The weekly review is the engine of GTD. Allen recommends scheduling 30 to 60 minutes once a week — same time, same place if possible — to:
- Clear all collection tools (in-tray, notebook, email inbox, voicemail)
- Capture any thoughts still floating in your head
- Review the past week and tie up loose ends
- Mark off completed next actions
- Look at the calendar — past for follow-ups, future to prepare
- Review the Waiting For list and follow up where needed
- Review every project and ensure each has a clear next action
- Review the Someday / Maybe list to promote or remove items
Use our free GTD Weekly Review checklist so you don’t miss anything.
A good weekly review leaves you with three things: a clear mind, a current system, and a realistic plan for the week ahead.
Step 5: Engage
This is the stage where you actually do the work. With everything captured, clarified, organized, and reflected on, choosing what to do at any given moment becomes much simpler.
How to Decide What to Work On
Allen suggests trusting your gut, supported by four criteria:
- Context. What can you actually do given where you are and what you have available? At your desk, on the road, on a phone call?
- Time available. How much do you have? Five minutes between meetings calls for different work than a free afternoon.
- Energy available. What do you have the mental capacity for right now? Keep some low-energy tasks on hand for low-energy moments.
- Priority. What matters most given your goals and roles?
Always work on one task at a time. Multitasking creates the illusion of progress while reducing actual output.
Setting Up Your Workspace
GTD works best with a dedicated workspace that’s ready to go whenever you sit down. Allen recommends matching setups at home and work so you can be effective in both. The basic kit includes a writing surface, two paper trays (in and out), pens, paper, a stapler, file folders, a labeler, a calendar, and a wastebasket — plus whatever digital tools you already use.
The four categories that can stay in your workspace without action attached: supplies, reference material, decoration, equipment. Everything else goes in the in-tray.
Color Coding Your GTD System
After mastering the basics, many GTD users add color coding to make the system more visual and faster to navigate.
A common scheme:
- Blue for next actions
- Green for projects
- Yellow for waiting for
- Purple for someday / maybe
- Red for calendar / time-specific items
Apply the same colors to digital labels, paper lists, and calendar entries. Keep the palette small — five distinct colors is plenty. Too many colors lose meaning fast.
Long-Term Planning: The Six Horizons of Focus
GTD isn’t only about today’s tasks. Allen describes six “horizons of focus” that connect daily action to long-term purpose. Each level should align with the one above it.
Ground: Current Actions
Today’s tasks, errands, calls, and reminders.
Horizon 1: Current Projects
Everything currently on your projects list.
Horizon 2: Areas of Focus and Accountabilities
The roles and responsibilities your projects support — relationships, health, finances, home, career, community. Use our free Areas of Focus and Accountabilities template to map yours.
If a role has no projects on the list, that’s a signal — something is being neglected.
Horizon 3: One- to Two-Year Goals
Where do you want to be in one to two years across each area of focus? Use our free 1-2 Year Goals template to write a SMART goal for each one.
Horizon 4: Three- to Five-Year Vision
The bigger picture — what kind of life, career, or business are you building toward over the next several years? Use our free Long-Term Visions template. Review and revise this annually.
Horizon 5: Life Purpose
The deepest level — what is your life ultimately for? What are your core values? For an organization, what’s its purpose, and what does it stand for? Use our free Life Purpose template to put it on paper. Review yearly.
Every level should reinforce the one above it. If your daily actions don’t ladder up to your areas of focus, your goals, your vision, and ultimately your purpose, the system isn’t pulling its weight — and the weekly review is where you catch the gap.
The GTD Flowchart
Once you’ve internalized the system, a single flowchart can replace pages of explanation. Run any task through five yes/no questions — actionable? a project? two minutes? delegate? time-specific? — and it lands in the right list.
We’ve built an interactive GTD flowchart that walks you through the workflow one question at a time, plus a printable PDF version you can pin above your desk. See the full GTD flowchart and workflow page.

My name is
Fabulous set of printables — thank you for sharing! One suggestion for improvement — the columns of the Someday/Maybe list don’t seem to make a lot of sense. Maybe something like Date – Idea – Review Date?
Thank you, this is fantastic!
Very helpful thank you very much I needed to read this to better understand the process and the GTD plan will most definitely help organize my brain.
