Be on the lookout for Behavior Change Secret Agents in your life. I had one for 40 years by the name of Frank W. Tate. I didn’t call him a Behavior Change Secret Agent back then. I called him my close friend. In truth, all close friends are secret agents in the way they infiltrate our toughest defenses, surprise us with their honesty and support and create a lasting influence on our lives that we often cannot fathom.
