GTD (Getting Things Done)

Getting Things Done (GTD) is David Allen’s productivity method, published in 2001 and updated in 2015. The core claim: your brain is for having ideas, not holding them. A trusted external system captures everything, so your mind can focus without the low-grade anxiety of trying to remember open loops.

The five steps

1. Capture — Everything that has your attention goes into a single inbox (paper, app, email, voicemail — all one place).
2. Clarify — Process each item: Is it actionable? If yes, what’s the next physical action? If no, trash, someday/maybe list, or reference.
3. Organise — Put clarified items in the right place: Next Actions list (by context — @phone, @computer, @errands), Projects list, Waiting For list, Someday/Maybe list, Reference files.
4. Review — Weekly review of all lists. This is the most important habit and the one most GTD practitioners skip. Without the weekly review, the system rots.
5. Engage — Choose what to do based on context, time available, energy, and priority.

Why GTD matters for task management tool selection

GTD has strong opinions about tool features:

• Context-based filtering — GTD requires tagging tasks by context (@phone, @email, @errands) and filtering by active context. Todoist does this natively with labels and filters. ClickUp requires custom field setup. Monday doesn’t support it cleanly.
• Natural language capture — The capture step needs to be frictionless. Todoist’s natural language input is the best in the category. Anything that adds 3+ clicks to task creation fails the GTD capture test.
• Next Actions view — You need a view of all actionable next steps across all projects. Todoist’s filters handle this well. Asana’s “My Tasks” approximates it. ClickUp requires a custom view.
• Waiting For list — Tasks delegated to others that you’re waiting on. Most tools handle this via tags or custom status. Todoist’s label system (@waiting) is the cleanest implementation.
• Weekly review support — A weekly review needs a consistent ritual: all inboxes cleared, all projects reviewed for next actions, calendar scanned. Any task manager can support this with a recurring weekly review task — but Todoist’s natural language (“every Monday at 9am review all projects #admin”) makes the habit more robust.

The two most common GTD failures in software

1. Using a project manager as a GTD tool. Asana and ClickUp are project-management tools — they assume work is organised in projects with team members. GTD assumes work is organised by contexts with one trusted system. The mismatch creates friction: you create an Asana project for “Personal,” fight with team settings, and abandon the system in week 3.

2. Skipping the weekly review. The weekly review is what makes GTD a trusted system. Without it, the inbox accumulates, the project list goes stale, and next actions are wrong. Every GTD practitioner who abandoned the method stopped doing the weekly review first.

Tool recommendations for GTD

• Best GTD fidelity: Todoist Pro ($4/mo) — natural language capture, filters for contexts, recurring review tasks, inbox model
• Best GTD for power users: Akiflow ($19/mo) — GTD-native with daily planning ritual, time-blocking, and fast capture
• Best GTD in ClickUp: Possible but requires setup — custom fields for context, saved views for next actions, a separate personal space for non-work tasks
• Not recommended for GTD: monday.com (no context filtering), Asana (team-first, not solo-system friendly)
