In her TEDx talk, Just One No, Kathryn Phillips explores the personal side of courageous decision-making—and the experiences that ultimately helped shape The Anatomy of a Good Choice™.

Long before she taught ethical decision-making in the classroom or spoke about it from the stage, Kathryn was practicing it in her own life: recognizing when something wasn’t right, weighing what mattered, finding the courage to act, and accepting that a good choice does not always feel like an easy one.

Just One No reflects a belief at the heart of Kathryn’s work today: our professional work can only rise to the level of our personal work. Character, courage, discernment, and intentional choice are not skills we turn on when we arrive at work—they are built through practice.

The talk offers a deeply personal look at what it means to find your voice, draw a line, and make the choice that changes what comes next.
