Why I prioritise sleep above all else before a big presentation

A big presentation is judged in the room, but it is built long before I step onto the stage. Preparation for live television, a leadership conference or a company keynote includes research, rehearsal and technical checks, yet the condition I protect most closely is sleep. It affects how quickly I find the right word, whether a room feels welcoming and how well I listen when the plan changes. Those are not soft extras; they are central to the job of being a credible speaker.

I do not treat sleep as a reward for finishing the work. If I sacrifice it to polish one more slide, I borrow energy from the exact faculties the audience needs. My aim is not to appear untouched by nerves. It is to arrive settled enough that nervous energy serves the message rather than hijacking it. That principle matters everywhere, but it becomes especially practical in Australia, where a speaker may cross time zones, wake in an unfamiliar hotel and give an early-morning keynote after a long international flight.

Sleep is part of the performance

A tired speaker does not simply look tired; the cost appears in the performance. Working memory becomes less reliable, verbal fluency slows and self-monitoring turns noisy. I may remember the structure of a talk but lose the natural bridge between two ideas. My face can also betray fatigue before my words do. These are physiological changes, not evidence of weak preparation, and they are difficult to conceal under studio lights or in a theatre full of attentive faces.

During deep sleep, the brain helps consolidate newly learned material and regulate emotional responses. After a short night, I can sound technically correct yet feel strangely detached from the audience. Caffeine may sharpen my first hour, but it does not restore the judgement, patience or recovery that good sleep supports. Before a presentation that asks for trust, honesty and clear decision-making, acute sleep deprivation creates an avoidable liability.

This is why I prioritise sleep above an extra rehearsal cycle. One useful rehearsal can improve a weak section; adequate sleep improves the person delivering every section. It steadies my breathing, gives my voice room and helps me remain curious when an unexpected question arrives. For leaders, that composure is valuable in its own right. People pay attention to whether a speaker has the bandwidth to absorb the room, not merely whether they can recite a polished script.

A sleep plan that travels well

Australia gives fresh meaning to the phrase “body clock”. The country spans three broad time zones, and a journey from Perth to Melbourne or Brisbane can shift the body’s clock by several hours. No amount of urgency repairs that shift on its own. When I know an overseas trip will end with a major speaking date, I keep my sleep and wake times as consistent as practical, rather than waiting until I land to improvise.

A reliable plan starts with wake time rather than bedtime because a consistent cue supports my circadian rhythm. I get daylight soon after rising and use caffeine earlier rather than as a rescue measure. On a clear Sydney morning, a brisk walk beside Bondi is a practical way to signal daytime to the body; in Melbourne, breakfast by a window serves the same purpose. Light helps anchor the clock, while stable routines give the nervous system less to negotiate.

Hotels add their own complications: firm pillows, street noise, shared walls and air conditioning designed for someone else’s comfort. I ask for a quiet room, keep my usual wake-up routine and avoid treating the hotel minibar as a midnight stress strategy. I also plan meals around Australian event schedules, where dinner may run late and an early call time can follow. Small choices protect the one resource that cannot be negotiated during the final countdown.

The final twenty-four hours

In the final twenty-four hours, my priority is to stop asking my brain to absorb more than it can hold. I do useful preparation, confirm the run of show and pack what I need, then close the laptop. Reading every slide again rarely rescues a talk that is structurally sound. A short walk, a calm shower and a low-stimulation evening help my attention narrow rather than scatter. The goal is not to feel perfectly rested; it is to arrive functional and present.

On the day, I eat familiar food, hydrate and keep caffeine moderate. If the schedule allows, a brief nap can take the edge off without replacing a full night; I would rather rely on that recovery than arrive wired and brittle. Before going onstage, I warm up my voice gently, move my shoulders and take slow breaths. These small rituals reduce the chance that nerves arrive as a rush of words.

This approach also reflects the thinking I bring to This Girl Is On Fire. The platform is about women using their voice, ambition and influence without losing their wellbeing to the demands of success. A presentation is one high-pressure event; a career is a long series of them. Protecting sleep is a practical way of treating energy as a responsibility rather than an endless resource to spend. It also reminds me that resilience is not the same as pushing through every sign of depletion.

Calm is a strategic advantage

Calm is not merely pleasant for the speaker; it changes the exchange with the audience. When I am properly rested, I can notice a look of confusion, pause without panicking and recover from a clumsy answer. I can also disagree respectfully and stay open to a better point. That flexibility matters in a room where leaders are expected to speak with conviction without turning conviction into defensiveness.

Australian audiences often favour direct speech, informal warmth and a bit of larrikin humour. In a Sydney boardroom or a Melbourne conference hall, an over-ceremonious delivery can feel distant, while a talk built on real stories can feel like a good yarn rather than a sales pitch. Sleep helps me find that balance. It gives me enough awareness to read the room, adapt the pace and use humour without forcing it.

I am also conscious of the wider message behind the Kiflimally approach: wellbeing should fit into a demanding working life, not create another performance. Sleep before a keynote is not a glamorous routine, and it is not a cure for every difficulty. It is one honest boundary, supported by ordinary habits that help a woman remain alert, grounded and able to make good decisions. That is a form of leadership in itself.

Speaking well when the stakes are high

My corporate speaking work is often commissioned for moments when an organisation needs more than an engaging talk. Leaders want resilience, clarity and a message that survives contact with a busy calendar. I therefore discuss energy and preparation with clients, but I never treat exhaustion as proof of commitment. A speaker who is alert can listen, improvise within the brief and leave the audience with something precise. A speaker who is depleted may deliver the right words while missing the human point.

The Australian events market makes this especially concrete. Corporate organisers commonly book through agencies, work to tight production schedules and choose dates around national and state public holidays. Keynotes may be scheduled at breakfast events in Brisbane or evening gatherings in Perth, followed immediately by another engagement. The entertainment may be polished, but the reality includes interstate travel, hotel check-ins, microphone tests and last-minute timing changes. Good preparation accounts for that operational reality instead of pretending the stage exists in isolation.

A sleep-first plan also changes what we ask of the wider event team. Producers can build in realistic travel buffers, protect a quiet final evening and avoid turning the green room into an improvised office. It supports better pacing from sound check to questions. When I am rested, I am less likely to impose unnecessary control on the room, and the collaboration becomes calmer. That is a better outcome for the client, the crew and the people in the seats.

A final safeguard is to treat one imperfect night as information, not a verdict. If sleep has been poor, I adjust the day rather than pretending fatigue has vanished. I use familiar material, ask the producer to clarify the flow and avoid adding new ideas at the last minute. This is not an excuse to lower standards. It is a way to deliver them. When I speak at my best, the audience experiences confidence, curiosity and trust, and the room feels easier because the person leading it is working with a rested mind.
