The Next Action
Allen's tactical masterpiece — the single, physical, visible activity that moves a project forward — transformed by AI from a problem of identification into a problem of selection among overwhelming simultaneity.
The next action is GTD's signature tactical contribution: the insistence that every project be reduced to a single concrete physical step, specified with enough precision that the body can act on it without further deliberation. Not "plan the event" (a project) but "call the caterer to confirm the menu." The discipline converts amorphous projects into manageable sequences and dissolves the definitional logjam that Allen observed in most people's paralysis. The power of the technique lies in its linearity: one step at a time, each revealing the next. AI has not eliminated the usefulness of next actions but has inverted the cognitive challenge they pose — from identification (which step?) to selection (which of many available steps?), and from sequential execution to parallel branching across a landscape of simultaneously available options.

Allen observed through decades of consulting that most paralysis in knowledge work was not motivational but definitional. People were not lazy; they were
