The Script
At a remote airfield, two skydiving instructors brief their students. They stand on opposite sides of the hangar, each with a group. The first instructor is meticulous, walking his students through a fifteen-point safety check, drilling the emergency procedures for every conceivable malfunction. His group is focused, faces tight with concentration, memorizing the choreography of survival. Across the hangar, the second instructor is doing something different. He has his group practice a single, simple action: finding and pulling the rip-cord on their training harness, over and over, until it's pure muscle memory. He doesn't lecture on the dozen things that can go wrong; he builds deep, reflexive confidence in the one thing that must go right. When the plane ascends, one group is mentally rehearsing a catalog of fears. The other is anchored to a single, positive action.
That difference in approach—training for disaster versus training for success—is what fascinated Riley Kehoe. As a former search-and-rescue team lead who spent years making life-or-death decisions in moments of extreme stress, Kehoe saw how easily people become paralyzed by analyzing all the potential negative outcomes. He noticed that the most effective individuals were those who had an instinct for the one action that mattered most, rather than a plan for every failure. He wrote "Three Seconds of Courage" as a way to retrain our instincts, shifting our focus from the thousand things that could go wrong to the one decisive move that makes everything right.
Module 1: Redefining Courage as a Daily Practice
We often frame courage as something reserved for heroes in extraordinary moments. This book argues that's a misconception. Courage is a skill, a choice, and a daily practice built through small, intentional acts.
The author introduces a powerful idea: courage is cultivated through small, daily choices and imaginative play. Kehoe shares how she and her sisters played a game called "Survivors" on their New Zealand farm. In this game, she created an alter ego named Elizabeth, a persona who was brave and assertive. When faced with real-life challenges, like shyness or bullying, she would ask herself, "What would Elizabeth do?" This simple question allowed her to practice being courageous. She was, in effect, rehearsing bravery. This was about using imagination to build the identity she wanted to inhabit. Over time, the line between Riley and the courageous Elizabeth blurred, and the practiced traits became her own.
This leads to a crucial insight. Courage is a conscious choice in the face of fear. The book uses the gripping story of the tsunami to illustrate this. After surviving the initial wave, Kehoe’s parents made a deliberate decision. Instead of evacuating with other family members, they chose to stay behind in the devastated area. They were exhausted. They were terrified of another wave. Yet, they decided to help others. This was an act performed despite fear. Courage, the book suggests, is that pivot point. It's the moment you acknowledge the fear but refuse to let it make the decision for you. It’s a verb, an action you take.
From this foundation, we learn that courage often requires choosing vulnerability over comfort or pride. Kehoe was born partially deaf, a fact she hid for years out of pride and fear of judgment. While working as a server, she made an error on an order and faced the wrath of an intimidating chef. In that moment, she had a choice: stay comfortable in her secret or risk vulnerability. She chose the latter, confessing her hearing impairment. The chef's anger immediately dissolved. He revealed his own daughter was deaf and became her strongest supporter. That single act of overcoming pride didn't just save her job; it turned a hostile relationship into one of grace and connection.
So what's the takeaway here? This module reframes courage as a series of small, accessible decisions. You build your courage muscle through practice, just like any other skill. It's about choosing to act despite fear and leaning into vulnerability, even when your pride tells you to hide.
