Each stage represents a unique mindset and requires a unique teaching method. For instance, somebody in contemplation doesn’t want a grocery listing—they want empathy and perspective.
Coaches skilled in TTM study to “meet the client where they are.” This means recognizing whether or not they’re considering change, constructing plans, or just making an attempt to remain on monitor.

Coaches can use this idea to assist purchasers construct confidence by means of mastery experiences, modeling (observing others), and constructive reinforcement. For instance, if a shopper says, “I always fail at diets,” you may ask, “Can you think of a time when you stuck with something challenging?” Recalling that win—even when it’s unrelated to meals—builds perception that change is feasible.
