Context in GTD: sort actions by where you can do them

A GTD context is where, with what, or with whom an action can be done — sort by it and you only see the tasks your current situation actually allows.

Why it works

You can only do what your current situation allows — errands need to be out, calls need a phone, certain tasks need a specific person present. Grouping actions by context means that in any given moment you see only the things you can actually do right now, removing the friction of scanning an undifferentiated master list and deciding what is even possible. The deeper reason this works is that a master list forces two decisions at once — "what can I do here?" and "what should I do next?" — and the first one is pure overhead you pay every time you look. Context lists pre-answer the feasibility question at filing time, when you are already thinking about the task, so that at the moment of choosing you are only doing the second, genuinely useful comparison. It also changes what a list is for: a context list is not a record of everything outstanding, it is a menu for a specific situation, which is why a good one is short enough to read without scrolling.

How to do it

1. Tag each next action with the context it requires (@calls, @errands, @computer, @home, @agenda-with-X).
2. When you have a window, open the matching context list rather than the whole pile.
3. Pick from what is actionable in your current situation instead of re-evaluating everything.

Evidence

A practitioner organizing scheme rather than a tested intervention, though it is consistent with choice-architecture and cognitive-load principles: narrowing the visible option set to what is currently feasible reduces decision friction. Iyengar and Lepper’s choice-overload experiments found that a smaller set of options can produce more follow-through than a larger one, which supports keeping each context list short enough to act from. (mechanistic)

Contexts are a practical convention; for some people priority or energy level is a more useful sorting axis than location-based context.

Common mistake

Building elaborate context categories you never actually consult, or using a single giant list so you are always wading past tasks you cannot do right now.
