Getting
Things
Done
Your brain is for having ideas, not holding them. The GTD system captures everything, clarifies what matters, and lets you work with a mind like water.
Core Idea
Your Brain Is a Terrible Office
David Allen's central insight is deceptively simple: your brain is optimized for processing ideas, not storing them. Every task you try to hold in mental RAM creates a subtle background anxiety — your mind's reminder system firing on a loop. GTD short-circuits that loop.
The solution isn't a new app or a busier schedule. It's a trusted external system that holds your commitments so your brain can stop nagging you. Capture everything. Clarify each item. Organize it. Review regularly. Engage with full focus — the "mind like water" state.
Trusted System
The GTD system only works when you trust it completely. Your brain releases its grip only when it knows nothing will fall through the cracks.
Next Actions
Every project must have a defined next physical action — a verb-led task you can execute today. Vague to-dos create hesitation. Specific actions create flow.
Mind Like Water
A calm pond responds to a pebble with perfect proportionality — then returns to still. GTD gives your mind that same quality: react appropriately, then reset completely.

The 5-Step GTD System
Select each step to understand how Allen's workflow moves everything out of your head and into action.
STEP 1 OF 5
Capture
Capture 100% of what has your attention — ideas, to-dos, commitments, concerns. Get them out of your head and into a trusted system.
Key Tool
The Inbox — a single place to capture everything. Physical notebook, app, email, voice recorder. One capture point.
Remember
Your brain stops reminding you once it trusts you'll capture it. Capture creates mental space.
The Golden Rule
The Two-Minute Rule
If it takes less than two minutes, do it now.
Don't add it to a list. Don't schedule it. Don't think twice. Execute immediately and be done. This single rule eliminates a massive category of accumulation that silently clogs most people's systems.
The two-minute threshold is not arbitrary — it's the point where the overhead of tracking exceeds the cost of just doing.

How It Works
The GTD Decision Tree
Every item that enters your life travels through this logic.
01
Inbox
Something enters your life — an email, a thought, a request, a task.
02
Is it actionable?
If no → Trash it, file it as reference, or park it in Someday/Maybe.
03
One action?
If yes and < 2 min → do it now. If yes and > 2 min → define the next action.
04
Organize
Calendar for time-specific. Next Actions list by context. Projects list for multi-step.
05
Engage
Choose from your organized, trusted system. Context + time + energy = perfect decision.
Context Lists

Tag every action with its context so you only see what's relevant right now.

Community Insights
Passages that stop people mid-read and change how they work.
"Your brain is a terrible office. It stores ideas, not systems. Move the thinking out of your head."
"The enemy of GTD is the belief that you can keep everything in your head. You can't."
"A project is any desired outcome that requires more than one step. That's all it is."
"Next actions should always be physical, observable, and complete. 'Work on the proposal' is not a next action. 'Draft the opening paragraph' is."
"If something is on your mind, it's usually because it should be on your mind. Capture it, process it, and let your mind go."
"You don't need a perfect system. You need a system you'll actually use."

Action Steps
Concrete moves to install the GTD system in your life this week.
The Two-Minute Rule
If a task will take less than two minutes, do it now. Don't put it in a list. Don't schedule it. Just do it. Two-minute tasks left on lists never get done — they just create clutter.
Do a Brain Dump Today
Open a blank document or paper. Write everything on your mind — every task, worry, commitment, idea. Don't organize. Don't edit. Just capture. All of it.
Inbox Zero, Every Day
Your inbox — email, messages, notifications — should hit zero at least once daily. Each item: do it, delegate it, defer it, or delete it. No passive storage.
Define Your Next Action
Pick one stuck project. Ask: what is the very next physical action required to move this forward? Write it down. Vague commitments are mental clutter.
Weekly Review: Every Friday
Block 60 minutes every Friday to: clear your mind, review all lists, capture any new open loops, and set priorities for next week. This is the engine of GTD.
A Place for Everything
If something has a home, it lives there. If it doesn't, create one. Clutter is deferred decisions about where things belong. Assign a home to every physical object.
"You can do anything, but not everything."
