Exercising just before a mentally demanding task like public speaking is a powerful tactical tool. A single session releases dopamine and serotonin, directly enhancing prefrontal cortex function for better focus, attention, and quicker reaction times, improving overall cognitive performance on the spot.

An analysis of 495 "Shark Tank" pitches revealed a key differentiator for success: hand visibility. The best pitchers immediately used hand gestures, often a wave, upon entering. Hiding hands is a primitive cue for distrust, making it difficult for an audience to feel safe and trust you.
Sam Altman's verbal response to a question about OpenAI's finances was reasonable, but his negative body language and audible sigh—perceptible only on video—completely changed the message's reception. This highlights how non-verbal cues in video interviews can undermine a leader's intended message, a critical lesson in the age of multimedia communication.
Pausing between sentences signals a conversational opening and invites interruption. To maintain control and build suspense, use a "power pause" in the middle of a sentence, just before delivering the most important information. This creates intrigue and holds the listener’s attention.
Communication extends far beyond words. How you carry yourself—your posture, demeanor, and overall presence—is a constant broadcast that communicates your value and influence.
