The fear of public speaking is deeply rooted in our ancestral past, where performance could determine one's status within a tribe. This fear, known as FOPO (fear of people's opinions), constrains potential and stems from an ancient survival instinct that clashes with modern stressors. As we navigate contemporary challenges, our brains still react as if facing a sabertooth tiger, making it crucial to understand and reframe these fears to thrive in today's world.
