Public speaking

Public speaking

Holding a room, from the opening ninety seconds to the questions at the end.

If you have to speak at work rather than choosing to, this course is built for you. Not a stage technique or a TED-style performance course. The mechanics of holding a room: what to do with your breath, your pace, your structure and your nerves, in that order, because that is the order in which they actually break down.

Why this starts with the body, not the slides

Almost every client who arrives describing a “confidence problem” turns out to have a mechanical one. Under pressure, breathing moves high into the chest and stops refilling between sentences. The voice thins, the pace runs away, the pauses disappear, and thinking gets harder. Not because of nerve — because over-breathing lowers carbon dioxide, and low CO₂ narrows the blood vessels feeding the brain and reduces the flow through them (Willie et al., 2014). Layer ordinary acute stress on top and the effect compounds: even mild uncontrollable stress produces a rapid, measurable drop in prefrontal function: the exact capacity you need to hold a structure in mind while speaking (Arnsten, 2009).

None of that is a character flaw. It is physiology, and physiology responds to training a great deal better than it responds to being told to relax. Slowing the breath to roughly six breaths a minute shifts the markers of parasympathetic activity, which is the closest thing to an “on” switch for calm that the evidence currently supports, on a small but consistent base of studies (Giorgi & Tedeschi, 2025). This course starts there, in lesson one, before a single word about structure.

What the twelve lessons cover

The course runs in the order a talk actually falls apart, not the order most advice assumes:

Diagnosis first. Lesson two is a recording of yourself, watched back before anything is taught. Almost every client hears their own two or three habits within the first minute, which is faster and more convincing than a list of tips.

The physical layer. Breath under pressure, pace, and the pause: the thing that goes missing first and is hardest to get back, because a pause under pressure feels like a gap for the room to fill.

Structure that survives being interrupted. Opening in ninety seconds, a shape that holds when a question arrives at slide four, and how to land a point so the room actually retains it rather than just hearing it.

Delivery under real conditions. Stillness, hands, eye line, and the specific discipline of handling a question you didn’t prepare for, plus a lesson on rehearsing in the wrong conditions on purpose, because a skill that only works in a calm room in front of no one is not a skill yet.

What actually lasts. The final lesson is not “more tips.” It is what to keep doing after the course ends, since the entire point is a habit that survives contact with an actual meeting.

Who this is and isn’t for

This is for people who present at work: board updates, all-hands, conference talks, client pitches, and want the anxiety to stop taking the voice with it. It is not a substitute for clinical treatment of a diagnosed anxiety disorder, and if public speaking is one symptom of a broader difficulty rather than a standalone problem, a GP or therapist is the right first call, not a course.

Twelve lessons, roughly two hours fifteen minutes end to end. Read them in order. Each one assumes the last.
