To manage anxiety while speaking, adopt the 'One Idea, One Breath' model. The key is to make your out-breath significantly longer than your in-breath while delivering a single idea. This extended exhalation activates your parasympathetic nervous system, lowering your heart rate.

Instead of using psychological 'mind tricks' (a top-down approach), focus on physiological interventions first. By controlling your breathing and vocal mechanics from the 'bottom-up,' you regulate your nervous system directly, which in turn calms your mind.

A seasoned speaker shares a story of nearly backing out of a panel minutes before going on stage due to a severe panic attack. This is normalized by his co-host, who confirms that feeling nerves and anxiety before speaking is a universal experience for professionals at all levels.

Deep belly breathing, with a focus on a long exhalation, slows the autonomic nervous system and calms physical symptoms of anxiety like a shaky voice. It's a physiological hack to manage the fight-or-flight response.

To combat presentation anxiety, arrive early and have a casual, human conversation with one or two people in the audience. This simple act transforms an intimidating crowd into a group of individuals, making the experience feel more like a conversation and calming you down.

A host recounts having a debilitating panic attack minutes before moderating a panel at a major conference. This highlights that professionals who appear calm on stage can experience intense nerves, anxiety, and self-doubt, reinforcing that such feelings are normal for anyone, regardless of experience.

Sam Harris argues that the most effective way to conquer stage fright isn't mental exercises like mindfulness, but repeatedly engaging in the feared activity. This process, similar to Cognitive Behavioral Therapy, retrains the nervous system by demonstrating that the outcome is not catastrophic, thereby desensitizing the fear response.

To manage public speaking anxiety, communication expert Matt Abrahams advises focusing on deep belly breathing where your exhale is twice as long as your inhale. Just two or three of these breaths can slow your nervous system, lower your heart rate, and normalize your voice, providing an immediate calming effect.

To combat severe physical anxiety that caused him to fail his first Facebook interview, Ryan Peterman got a prescription for beta blockers. These drugs block adrenaline's physical effects, like a pounding heart or shaking hands, allowing him to stay calm and pass his full-time interview loop.
