Use a five-second micro-start to breach the initiation threshold

Commit only to the first five seconds of an action — not the full task.

Why it works

The initiation problem is not a task-size problem; it is a starting-transition problem. The brain treats "begin the report" as a large, ambiguous demand and defers it. Redefining the commitment as "open the document and type one word" targets the threshold directly: a tiny, concrete action that the brain can evaluate as low-cost and low-risk, which is enough to trigger the action system.

How to do it

1. Identify the exact first physical action required to begin (open the app, sit at the desk, pick up the pen).
2. Commit only to that first action — not to finishing or even continuing.
3. When you complete the micro-start, you may stop. Most of the time, inertia carries you forward.

Evidence

Consistent with Fogg’s behavior model (motivation × ability × prompt) and with activation-energy research: reducing the perceived cost of initiation is the single lever that most reliably moves intention to action. The specific "five seconds" is a practitioner heuristic, not a studied interval. (mechanistic)

No direct RCTs on the micro-start format. The mechanism is solid; the specific timing is a practical convention.

Common mistake

Using the micro-start as a trick to "force" yourself into a long session, then feeling resentful when the task runs long — the technique works best when the exit at five seconds is a genuine option.
