Getting Things Done (GTD) explained: the 5 steps, with a worked example

Daniel Gavalec · Updated October 13, 2026

The Getting Things Done method (GTD) is David Allen's system for getting every commitment out of your head and into trusted lists, so you can decide what to do next without stress. It runs on five steps – capture, clarify, organize, reflect, engage – plus one weekly habit that keeps it all honest. Below you will find each step in plain English, the decision flow, a real worked example and a printable weekly review checklist.

What is Getting Things Done?

David Allen published Getting Things Done: The Art of Stress-Free Productivity in 2001 and released a revised edition in 2015. The premise is simple: your mind is good at having ideas and bad at holding them. Every unfinished commitment you keep only in your head – "call the dentist", "fix the client's login bug", "maybe learn Spanish" – nags at you and takes attention from whatever you are doing.

GTD fixes this with an external system you trust completely. Once everything is captured and sorted, you can look at your lists and pick the right thing to do in the moment, instead of reacting to whatever is loudest.

Research backs up the core idea. Masicampo and Baumeister (2011) found that unfinished goals cause intrusive thoughts, and that making a concrete plan for the goal – not finishing it, just planning it – made those thoughts fade. That is exactly what GTD's "clarify the next action" step does.

The 5 steps of GTD

Clarify: the GTD decision flow (and the 2-minute rule)

Clarifying is where GTD earns its reputation. Take one item from your inbox at a time, top to bottom, and never put anything back in. For each item ask:

1. What is it?
2. Is it actionable?
   • No → trash it, file it as reference, or park it on someday/maybe.
   • Yes → continue.
3. What outcome do I want? If it needs more than one action, it is a project – add it to the projects list.
4. What is the very next physical action? Then:
   • Takes less than two minutes → do it now.
   • Someone else should do it → delegate it and add it to waiting for.
   • Must happen on a specific day or time → calendar.
   • Otherwise → next actions list.

The two-minute rule exists because tracking a tiny task costs more than doing it. Reply "Yes, Thursday works" now; do not write "reply to Anna" on a list. The rule applies while you process your inbox – it is not permission to chase every small thing during deep work.

GTD lists explained

Allen also suggests grouping next actions by context – @computer, @calls, @errands, @home – so you see only what you can do where you are. In a world where most work happens on one laptop, many people now group by energy or time instead ("15-minute tasks", "brain-dead tasks").

A worked GTD example: one messy Monday

Let's say you are a freelance designer. You sit down Monday morning, set a 10-minute timer and dump everything on your mind into the inbox. Then you clarify each item:

Ten minutes of clarifying, and the inbox is empty. Nothing is forgotten, nothing is in your head, and your next actions list is short enough to actually choose from. If the list is still long, a quick pass through the Eisenhower Matrix helps you decide what matters most today.

The GTD weekly review checklist (printable)

Allen calls the weekly review the critical success factor of GTD. Block 45–60 minutes at the same time every week – Friday afternoon works well because it closes the week. The David Allen Company's official checklist has three phases; here is our paraphrased version:

Pair it with a printable weekly planner if you like paper for the "plan" step.

How to run GTD in CORTEX

GTD works on paper, in a text file or in any app. If you want it to also feel rewarding, here is how the GTD lists map onto CORTEX – a free gamified productivity app – tasks, a one-click day plan, time tracking and habits, with XP, levels and real-life rewards. We will be honest about where it fits and where it does not.

A capture line that clarifies and organizes in one go looks like this: Send sitemap proposal to Corner Café tomorrow @10:00 ~30m !p1 #CornerCafe (with a goal named CornerCafe). CORTEX reads the date, time, duration, priority and goal from the text. Your weekly review itself can be a repeating task: Weekly review fri @16:00 ~45m *weekly.

The game layer is the part GTD never had: each finished next action earns XP and credits for rewards you define yourself. For people whose brains want a reward now, that small hit makes "process the inbox" a lot less grim.

Common GTD mistakes (and quick fixes)

• Over-engineering the setup. Twenty contexts and nested tags are procrastination with extra steps. Start with the seven lists above.
• Vague next actions. If a task sits for a week, rewrite it as a smaller, more physical step.
• Skipping the weekly review. Without it, lists drift out of date and you stop trusting them. Make it a recurring appointment.
• Using the calendar as a wish list. Only things that must happen on that day go there. For deliberately scheduling focus time, use time blocking on top of GTD.
• No place for deep work. GTD is great at what to do, weaker at protecting time to do hard things. Combine it with deep work blocks.
