Clarify each item into a concrete next action

For every captured item, decide what it is and the very next physical action.

Why it works

A vague entry like "taxes" stays on a list untouched because the brain has no executable instruction to run — it sees an undefined project and stalls. Forcing each item into a concrete next physical action ("download last year’s return") removes the in-the-moment decision cost that causes procrastination, so starting requires almost no deliberation.

How to do it

1. For each captured item ask: is it actionable? If not, trash it, file it as reference, or set it aside as "someday".
2. If it is actionable, define the single next physical action in concrete, verb-first terms.
3. If it takes more than one step, record the outcome as a project and clarify only the next action now.

Evidence

Consistent with implementation-intention research: specifying the concrete when/what of an action substantially raises the odds it gets done compared with a vague intention. Defining the next action is essentially building an implementation intention for each task. (rct)

The evidence is for specificity raising follow-through; GTD’s particular sorting taxonomy is practitioner structure layered on that principle.

Common mistake

Leaving items as vague nouns ("website", "mom") instead of concrete next actions, so the list becomes a pile of stuck projects you keep skipping.
