Getting Things Done: what if your head stopped being the system?
Getting Things Done, David Allen's methodology, moves every commitment out of your head into one trusted external system: capture everything, clarify what each item actually requires, organize the results into lists, review them weekly, and choose work from what the lists show. It suits people managing many open projects and anyone kept awake by the fear of forgetting. Allen's premise is that your mind is for having ideas, not holding them. Every commitment stored only in your head charges rent: it resurfaces during dinner, during meetings, at 03:00. GTD is the eviction process, and it is thorough rather than quick.
How do you start with GTD?
- Capture everything that has your attention into an inbox.
- Clarify what each item is and decide the next physical action.
- Organize actions and projects into appropriate lists (e.g., Next Actions, Projects, Waiting For).
- Reflect on your system with a mandatory Weekly Review.
- Engage with your work by choosing actions based on context, time, and energy.
Why does writing everything down change anything?
You know the loop: the same unfinished item surfacing in the shower, in a meeting, at 03:00. It loops because part of you does not trust that it is safely recorded anywhere. GTD's wager is that the trust can be built. Capture everything, without exception, and the looping quiets, because checking a list you trust is easier than rehearsing twenty open commitments.
The clarify step is the underrated half. Taxes is not a task; calling the accountant about the missing form is. Most procrastination on a list is really ambiguity, and deciding the next physical action while you are calm is far cheaper than deciding it under pressure later.
Where does GTD collapse?
GTD collapses at the weekly review, almost always. Capturing is fun and setting up lists is fun; sitting down every week to process and prune is not, and without it the system silts up until you stop trusting it. An untrusted system is worse than none, because now you maintain lists and worry. If you adopt one piece with full commitment, adopt the review.
The other honest warning is scale. GTD is the heaviest method on this site, and if your working life is one project and a manageable inbox, it is more machinery than you need.
A system you do not review is a museum of former intentions.
The classic mistake: Skipping the weekly review. The entire system's integrity relies on this regular maintenance to stay trustworthy.
How do you make it stick?
The Weekly Review is Non-Negotiable
This is the keystone of GTD. It's where you regain clarity, control, and trust in your system.
Define Physical Next Actions
Don't write 'Taxes.' Write 'Call accountant to schedule appointment.' Clarity prevents procrastination.
Use Context Lists
Organize your 'Next Actions' by the context needed (e.g., @Computer, @Phone, @Errands) so you can see what's possible right now.
What should you ask yourself after the first week?
- How did it feel to do a full 'brain dump' of everything on my mind?
- Which part of the weekly review process provided the most clarity?
- What kinds of items were clogging up my mental inbox without me realizing it?
Where do you go from here?
If full GTD is too much machinery, Personal Kanban keeps the trusted-external-surface idea at a fraction of the cost. Time Blocking turns GTD's next-action lists into hours on a calendar, and the Rapid Planning Method adds the why that GTD deliberately leaves out. Compare all 17 in the method index.
