Secure Will — convert the best option into a specific commitment
Close the conversation with a specific, self-declared commitment to a concrete next action.
Key takeaways
- What it is: Close the conversation with a specific, self-declared commitment to a concrete next action.
- Why it works: Conversations that end without specific commitment produce good intentions that evaporate within 48 hours. The Will phase forces the transition from option to action: the person names specifically what they will do, when, and what obstacles they foresee. This creates an implementation intention, which research shows substantially increases follow-through compared to goal-only commitment.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Accepting vague commitments ("I’ll think about it" or "I’ll try to do X soon") — which carry no implementation intention and reliably produce no behavior change.
Why it works
Conversations that end without specific commitment produce good intentions that evaporate within 48 hours. The Will phase forces the transition from option to action: the person names specifically what they will do, when, and what obstacles they foresee. This creates an implementation intention, which research shows substantially increases follow-through compared to goal-only commitment.
How to do it
- 1Ask: "What will you actually do, and by when?" — specificity is the active ingredient.
- 2Invite the person to rate their commitment on a 1–10 scale: "How committed are you to this?" Below 8, explore the gap.
- 3Ask: "What might get in the way, and how will you handle it?" — anticipating obstacles increases follow-through.
- 4Close with a clean summary: "So you’re committing to [specific action] by [specific date]. Is that right?"
What the evidence says
RCT / meta-analysisImplementation intention research (Gollwitzer & Sheeran) is among the most replicated in behavioral science: when-where-how specificity in commitments dramatically increases follow-through compared to intention alone.
Honest caveat: The implementation intention research supports the Will phase’s mechanism; the GROW model as a whole is a clinical framework that applies this and adjacent principles.

Common mistake
Accepting vague commitments ("I’ll think about it" or "I’ll try to do X soon") — which carry no implementation intention and reliably produce no behavior change.
IX Coach closes every session with a specific, named commitment — what you’ll do, when, and what might get in the way — then checks on it at the start of the next session.
