What is GTD (Getting Things Done)?

GTD (Getting Things Done) is a world-renowned productivity methodology by David Allen, published in 2001. Its core principle: move everything out of your head into a trusted external system, then manage it through five phases.

Definition

GTD (Getting Things Done) is a productivity system developed by David Allen. It addresses the Zeigarnik effect — the phenomenon where uncompleted tasks consume mental resources — by externalizing every "open loop" into a trusted system. Through five repeating phases (Capture, Clarify, Organize, Reflect, Engage), GTD achieves stress-free productivity by ensuring nothing falls through the cracks.

The 5 Phases of GTD

1. Capture
Record everything that has your attention — tasks, ideas, worries — into an external tool. At this stage, don't think about what to do with it; just capture.
2. Clarify
Process each captured item. Ask "Is this actionable?" If yes, define the specific next action. If it takes under 2 minutes, do it immediately.
3. Organize
Sort clarified items into four categories: Next Actions (@Next), Waiting For (@Waiting), Someday/Maybe (@Someday), Reference (@Reference). Maintain a separate Projects list.
4. Reflect
Conduct a weekly review of your entire system. Check all lists, update completed items, remove obsolete ones, and maintain trust in the system.
5. Engage
Based on your current context (location, time, energy, priority), choose the best action from your @Next list and execute it.

Email Memo and GTD Synergy

The most important — and most failure-prone — GTD phase is Capture. Simple Memo's ~1-second launch and one-tap send reduce capture friction to near zero. Memos arrive in your email inbox, which naturally serves as your GTD inbox. Gmail labels map perfectly to GTD's four categories.
