Stop Hiding Behind Your Slides
Dirk Daenen, the man who brought TEDx to Luxembourg, reveals the science and the secrets behind becoming a truly confident speaker.

You'd think the man who coaches Luxembourg's most compelling public speakers would have been born fearless on stage. You'd be wrong. Dirk Daenen, communication expert, TEDx Luxembourg organiser, and the person quietly responsible for some of the most-watched talks ever delivered on Luxembourgish soil, started out as an introvert dreading the spotlight. In this candid conversation on The Lisa Burke Show, he opens up about fear, failure, the science of self-confidence, and why one talk filmed in front of 75 people in Wiltz went on to rack up 13 million views.

If you have ever frozen in front of a room, gone blank at a podium, or quietly vowed to avoid public speaking for the rest of your life, this one is for you.

TED vs TEDx: What's the difference?

Most people have heard of TED Talks. Far fewer know what the differential for TEDx is, or how accessible it really is. A standard TED conference ticket starts at around $20,000. You'll be sitting next to the world's most powerful minds, but the barrier is enormous. TEDx events, on the other hand, are independently organised under strict licence from TED, run entirely by volunteers, and designed to bring big ideas to local communities. Here in Luxembourg, that licence belongs to Dirk Daenen, and he has been running it for years.

"I'm used to being the smartest person in the room as a teacher", Dirk says with a grin. "And then suddenly I'm surrounded by the most impressive people I've ever met: graffiti artists, photographers, scientists, a Belgian pop star. No money could pay for that.”

"Luxembourg is a small country. But the ideas we spread are HUGE. Over 20 million views and counting."

The fear is real – and it starts at school

Up to 80% of people report some fear of public speaking. The academic figure sits closer to 40%. But according to Dirk, the number is almost beside the point, because wherever you land on that scale, the roots are almost always the same.

"We are doing a quantitative survey right now", he explains, "asking people about their childhood experiences. And what we are finding is that most people who identify as having a fear of public speaking can point to a specific moment at school where it all started.”

A teacher who snickered. A classroom that laughed. A presentation that went badly and was never properly supported. These are not trivial memories. Dirk calls them what they are: trauma.

"If you do it badly, you end up with people carrying post-traumatic stress disorder because of something that happened in front of a classroom.”

It is why his PhD research [yes, he is also completing a doctorate] focuses on finding the most effective way to teach public speaking to 16-year-olds, with the minimum possible trauma and the maximum boost to self-confidence. His dream: one full year of public speaking on the Luxembourg school curriculum. Not optional. A core subject, like French or German.

"Europe's biggest social failure?" he asks. "We have an amazing education system. And yet we do not teach the one skill you need in every single job, every single day."

The science of self-confidence

Dirk is a researcher as much as a coach, and he brings the science of psychology into every conversation about communication. The key framework he returns to is the work of psychologist Albert Bandura, whose four sources of self-efficacy – your belief in your own ability to do something – underpin everything Dirk teaches.

The first and most powerful source is mastery: actually doing the thing and surviving it.

The second is vicarious experience: watching someone just like you nail it, and thinking: if they can, so can I.

The third is social encouragement: the right kind of feedback, delivered with care.

And the fourth is physiological readiness: understanding that the butterflies you feel before speaking are not a warning signal. They are energy.

"I still get the butterflies. But I have taught them to fly in formation.”

Self-confidence, he explains, is not some vague quality you either have or don't. It is the sum of two measurable things: self-esteem (how much you value yourself) and self-efficacy (how capable you believe yourself to be). Public speaking, done well and in a safe environment, is one of the fastest ways to build both.

What actually works on stage

So what does Dirk actually tell the people he coaches? Here are some of the most practical insights from the conversation.

Your body will move whether you plan it or not. When you're nervous, adrenaline floods your system. Oxygenated blood pumps into your muscles. If you don't channel that energy intentionally, your body finds its own outlet: clicking pens, rotating wedding rings, crossing arms, hands shoved in pockets, the classic 'fig leaf.' The fix is not to stand rigid. It's to plan your gestures in advance. Identify your key words and decide how to show them physically. Do this for six months and those movements become automatic.

Preparation is not the same as memorisation. One of the most striking stories in this interview involves Emma Bale, the Belgian pop star who had performed for 60,000 people at Dour Festival but was terrified of a TED Talk. She memorised her speech so perfectly it sounded robotic. The humanity disappeared. Dirk had to coach her to re-introduce vulnerability: a planned, spontaneous-sounding moment at the start. 'It takes a lot of preparation to be spontaneous,' he says. Tony Blair knew this. So did every great performer you have ever admired.

The top 10 most-viewed TED Talks have no slides. Think about that the next time you spend three hours building a PowerPoint. Structure matters, yes. But the elements almost nobody teaches: voice, body language, audience engagement, are what people actually remember. The information-heavy slide culture in European education has produced presenters who hide behind their decks. Stop hiding. You are the presentation.

Watch people who are like you. Bandura called this vicarious experience. You don't need to imitate a world-famous orator. You need to see a normal person, someone at your level, stand up and do it well. That is why TEDx Luxembourg matters. Local people, on a real stage, sharing real ideas. 13 million views from a room in Wiltz. Proof that it is possible.

Just do it. There is no way around this one. Toastmasters. Improv classes. The TEDx stage. The school debate club your child has been avoiding. The skill builds only through exposure. 'I was a chef allergic to food,' Dirk says. 'I ate the food anyway. It wasn't poison. It was the best meal of my life.'

📅 Coming Up: TEDxLuxembourgCity – 12 May 2025

The next TEDxLuxembourgCity event, sponsored by the Ministry of Education, takes place on 12 May. The lineup includes a manga artist, acclaimed photographer Christian Clowers (whose images on climate change are, in Dirk's words, 'so visually clear they speak for themselves'), a university professor on the future of higher education, and – perhaps most excitingly – two student speakers chosen from a national idea competition open to every school in Luxembourg.

Applications to speak at future TEDx events, volunteer, or sponsor are always open. Visit the website below to get involved.

Parents: get your children speaking early. Teachers: create the safe environment they deserve. Adults: you are scared because you know it matters. That fear is information, not a stop sign.
