GTD: Get It Out of Your Head, Into a System

Knowledge work arrives as an endless stream of stuff: emails, half-promises, ideas, errands. Held in the head, each one becomes an open loop that nags without ever telling you anything useful. Working memory holds about seven items, so the rest simply leak out as low-grade anxiety.

GTD starts from an unflattering assumption: your subconscious is a bad reminder system. It nags you about the watch repair at midnight, never as you cycle past the shop.

Everything that has your attention goes into an in list: a notebook, an app, a single inbox you actually check. The barrier to adding something should be almost zero, because a capture tool you resist is a capture tool you will not use.

Start with one long session emptying your head of every open loop, from a stalled client proposal to a toothbrush that needs replacing. Nothing is too small or too vague to write down.

Process the in list item by item, in order. First question: is it actionable? If not, bin it, file it as reference, or park it on someday/maybe.

If it is actionable, three routes:

• Under two minutes, do it now, because tracking it costs more than doing it.
• Someone else's job, delegate it and log it on a waiting for list with the date.
• Yours and longer, defer it onto next actions.

This is the rule that does the heavy lifting. Not plan the launch, but draft the launch email to Camille. Not sort out hiring, but review the job description.

Spending ten extra seconds deciding what physically has to happen means your list only holds things you can start immediately. The thinking is already done, so the resistance to beginning collapses.

Anything needing more than one step is a project, whether it is a quarterly strategy or getting quotes for a new kitchen. The projects list holds only titles and intended outcomes, not detail.

Its job is to catch drift. When you review it, you check that every live project has at least one next action waiting. A project with no next action is a project quietly dying.

Tag next actions with where or with what they can be done: at the computer, in town, in the weekly one-to-one with your manager. Then picking work becomes a filter, not an agony.

Allen's four criteria, in order: what can I do here, what fits the time before my next meeting, what matches the energy I actually have, and only then, what matters most.

Allen calls it the critical factor for success, and he is not joking. Without it, lists rot and trust evaporates. Book thirty minutes or more, the same slot each week.

Check every project has a next action. Be honest about actions you will not touch and move them to someday/maybe or delete them. Scan someday/maybe for anything whose time has come. Then your head can genuinely let go.
