David Allen, in bytes
17 key learnings on David Allen's GTD method for capturing, organising and doing your work with a clear mind.
Learning 1 · Part 1
The idea
Allen argues that keeping commitments in your head creates stress. The mind is good at having ideas, poor at storing them.
Example
Remembering you need batteries only when you're nowhere near a shop.
Takeaway
Get everything out of your head into a trusted system.
Learning 2 · Part 1
The idea
Every unfinished commitment, from a big project to buying milk, is an open loop that quietly pulls on your attention.
Example
A vague 'I should call the bank' keeps resurfacing all week.
Try this
List every open loop you can think of.
Learning 3 · Part 1
The idea
GTD has five stages: capture, clarify, organise, reflect and engage.
Example
Most people capture in scattered places and skip clarifying, so lists become guilt piles.
Takeaway
Overwhelm usually comes from skipping a stage.
Learning 4 · Capture
The idea
Collect every task, idea and commitment in a small number of inboxes you trust.
Example
A notebook, an email inbox and a physical in-tray, emptied regularly.
Try this
Keep one capture tool with you all week.
Learning 5 · Capture
The idea
Allen suggests writing down everything on your mind, one item per note, until your head feels clear.
Example
Work projects, home repairs, birthdays, ideas, worries.
Try this
Spend 30 minutes on a full mind sweep.
Learning 6 · Clarify
The idea
For each item ask: is it actionable? If so, what's the very next physical, visible step?
Example
Not 'sort out the car' but 'call the garage to book a service'.
Takeaway
Vague tasks get avoided; specific ones get done.
Learning 7 · Clarify
The idea
If the next action takes less than two minutes, do it now. Organising it would take longer.
Example
Replying 'yes, Tuesday works' immediately instead of filing the email.
Takeaway
Small tasks done at once keep lists clean.
Learning 8 · Clarify
The idea
If an action takes longer, delegate it if someone else should do it, or defer it to a list or the calendar.
Example
Forwarding a request to the right colleague and noting it on Waiting For.
Takeaway
Every item gets a decision.
Learning 9 · Organise
The idea
Allen defines a project as any outcome that needs more than one action. Keep a list so nothing stalls.
Example
'Plan the offsite' is a project; 'email the venue' is its next action.
Try this
Give every project on your list a next action.
Learning 10 · Organise
The idea
Group next actions by where or with what you can do them: Calls, Computer, Errands, Home, Agendas.
Example
With ten minutes and a phone, open your Calls list.
Takeaway
Context lists make free moments productive.
Learning 11 · Organise
The idea
Track delegated items on Waiting For, park possible ideas on Someday/Maybe, and file non-actionable information as reference.
Example
A course you might take next year goes on Someday, not today's list.
Takeaway
Nothing is lost, and nothing clutters today.
Learning 12 · Organise
The idea
Only put on your calendar what must happen on a specific day or at a specific time.
Example
A meeting at 10 belongs there; 'start report' doesn't.
Takeaway
A calendar you trust is one you never overload.
Learning 13 · Reflect
The idea
Each week, get clear (empty inboxes), get current (update lists and projects), and get creative (add new ideas).
Example
Allen calls it the critical success factor that keeps the system trusted.
Try this
Book a recurring hour on Friday afternoon.
Learning 14 · Engage
The idea
In the moment, choose based on context, time available, energy available and priority.
Example
Low energy at 4 pm? Pick easy calls, not the strategy paper.
Takeaway
Trust your intuition once the lists are current.
Learning 15 · Engage
The idea
Allen describes levels from current actions up through projects, areas of responsibility, goals, vision and purpose.
Example
A daily action ('draft the proposal') serves a goal ('win two new clients this year').
Reflect
Do today's actions connect to what matters at higher levels?
Learning 16 · Engage
The idea
Plan projects as the brain naturally does: purpose, vision of success, brainstorm, organise, next actions.
Example
Planning a dinner party starts with why, then pictures the evening, then lists tasks.
Try this
Use these five steps on one project this week.
Learning 17 · Conclusion
The idea
The goal is a calm mind that responds appropriately to whatever comes, like water responding to a pebble.
Example
With everything captured, you can focus fully on a conversation instead of worrying about tasks.
Takeaway
GTD reduces stress, not the amount of work.

Your mind is for having ideas, not holding them. What's still on your mind that belongs on a list?
