Ever wonder why you snap, shut down, or people-please when you meant to stay calm? You might be caught in one of your nervous system's "protective defaults": fight, flight, freeze, or fawn.
In this video, I’m breaking down the science of why these stress responses occur, how they show up in your daily life (like in a tense meeting or a sharp email), and how to identify your specific default pattern.
Understanding these mechanisms is the first step toward regaining choice in how you react under pressure.
