Getting Things Done

David Allen's GTD methodology has helped millions achieve stress-free productivity since 2001. Its core insight is simple: your mind is for having ideas, not holding them. Get everything out of your head and into a trusted system.

The GTD philosophy

Getting Things Done starts with a radical premise: the reason you feel stressed is not because you have too much to do, but because you have too many undefined commitments rattling around in your head. Every email you need to reply to, every project you have been meaning to start, and every errand you must not forget occupies a slice of your mental bandwidth.

GTD provides a systematic process to externalize every commitment into a trusted system, then process, organize, and review it regularly so your mind can focus on execution rather than remembering.

The five steps of GTD

GTD consists of five stages. Capture means collecting every thought, task, or idea into an inbox, whether physical or digital. Clarify means processing each item to determine what it is, whether it is actionable, and what the next concrete step is. Organize means placing each clarified item into the right category: a calendar event, a Next Actions list, a Someday/Maybe list, a project plan, or the trash.

Reflect means conducting regular reviews, most importantly the Weekly Review, where you ensure your system is complete and current. Engage means actually doing the work, choosing from your organized lists based on context, time available, energy, and priority.

Mind like water

Allen uses the martial arts concept of mind like water to describe the ideal productivity state. When you throw a stone into a still pond, the water responds proportionally: a small stone causes a small ripple, a large stone causes a large ripple. The water does not overreact or underreact.

Similarly, when your system captures every commitment and your reviews keep it current, you can respond to each new input with exactly the appropriate level of effort. You stop carrying mental loops of things you are afraid to forget. The result is a calm, focused state where you can give full attention to whatever task is in front of you.

GTD in the age of overwhelm

When GTD was published in 2001, the average knowledge worker received roughly 40 emails per day. Today that number has multiplied, and email is just one of dozens of input channels. The GTD system remains sound, but the sheer volume of inputs means the Organize and Reflect steps can become overwhelming in themselves.

Many GTD practitioners find that their Next Actions list grows into the hundreds, creating the very decision fatigue the system was designed to eliminate. The solution is not to abandon GTD, but to layer a constraint on top of it: capture everything, but commit to only a handful of actions each day.

How octo.do applies GTD principles

octo.do embraces GTD's core insight that your mind should be free of open loops, then adds the constraint that GTD lacks. The three-column structure mirrors GTD perfectly: Today is your curated Next Actions list, Next is your short-term pipeline, and Someday is your Someday/Maybe repository.

The key difference is that octo.do enforces an eight-task limit on Today, preventing the Next Actions list from ballooning into an anxiety-inducing scroll. WSJF scoring replaces the manual Reflect step by automatically surfacing the highest-value tasks. The daily reset acts as a built-in mini Weekly Review. You get the peace of mind that GTD promises, with the focused execution that only a hard constraint can deliver.

Capture everything. Focus on eight. Start free with octo.do.
