1
Your brain is a terrible office. It stores ideas, not systems. Move the thinking out of your head.
The core insight that changed productivity culture: your mind is for having ideas, not holding them. Every open loop — every unfinished task you're mentally tracking — costs cognitive energy.
-
2
The enemy of GTD is the belief that you can keep everything in your head. You can't.
The amount of mental energy spent tracking 'what am I supposed to do?' is invisible but enormous. Externalizing it — even imperfectly — immediately frees up substantial mental bandwidth.
-
3
A project is any desired outcome that requires more than one step. That's all it is.
Allen democratizes the concept of 'project.' You're not managing a project — you're changing something that requires multiple steps. Everything from writing a report to planning a vacation counts.

4
Next actions should always be physical, observable, and complete. 'Work on the proposal' is not a next action. 'Draft the opening paragraph' is.
Vague next actions create hesitation. Specific, concrete next actions are actionable. The specificity is what makes it happen.
-
5
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.
Intrusive thoughts about undone tasks are the brain's attempt to not forget. Writing them down tells the brain: 'I've got this, you can let go.' It works.

You don't need a perfect system. You need a system you'll actually use.
Allen has seen thousands of elaborate productivity systems fail. The best system is the one that reliably captures everything and gets reviewed regularly. Simple and trusted beats complex and neglected.
How to apply Getting Things Done
Turn the ideas into something you can do this week.
The Two-Minute Rule
If a task will take under two minutes, do it now. Don't list it. Don't schedule it. Clear the small stuff so lists stay for real work.
Do a Brain Dump Today
Open a blank page and capture everything on your mind — tasks, worries, commitments, ideas. Don't organize yet. Empty the head first.
Inbox Zero, Every Day
Drive email and message inboxes to zero at least once: do, delegate, defer, or delete. No passive storage.
Define Your Next Action
Pick one stuck project and write the next physical action required to move it forward. Vague commitments are mental clutter.
Weekly Review: Every Friday
Block 60 minutes every Friday to clear your mind, review lists, capture open loops, and set next week's priorities. This is the engine of GTD.
A Place for Everything
Give every physical object and digital file a home. Clutter is deferred decisions about where things belong.
Set up capture tools
Choose one trusted inbox for capture — notebook, app, or voice notes — and put it where friction is lowest. If capture is hard, open loops stay in your head.
Capture every open loop
When something pops into your head today, write it into your capture tool immediately. Your mind is for having ideas, not holding them.
