People move when we engage their emotions. Yet we too often default to logic, authority, or habit. Not so moving.
To engage their emotions, try telling a story with them as the hero. Include a bit about where they are now, where they could possibly go next, and why. Say something about the challenges they will encounter, the help they will receive, and the positive outcomes they will enjoy. And most importantly, allow yourself to feel even little bit of the excitement, inspiration, anger, concern, courage, etc. that naturally comes up when you tell such a compelling story. If you feel it, they will, too.
In your corner,
