If someone is dreading a presentation, ask them what they think might happen, and they can usually tell you in great detail.
Not in vague terms. They know exactly which slide it happens on, which question they can’t answer, and roughly who asks it. They can describe the silence that follows, the walk back to their seat, and how the meeting carries on as if nothing happened.
That level of detail is worth noticing because it reveals something nobody ever tells them. They’ve been visualising all week. The same film, running again and again, and it ends badly every time.
The advice that misses the point
The usual advice is to visualise success: imagine things going well, and see yourself feeling confident and composed.
It almost never works, and the reason is in the sentence itself. It assumes you need to learn this technique, when in fact you have been practising it, unpaid and without instruction, for days. You are not a beginner at mental imagery. You are rather good at it. You have simply been rehearsing the wrong thing.
Imagining an action draws on much of the same machinery in the brain as performing it. That is why mental rehearsal is taken seriously in sport, and why the disaster film has such a grip. Every time you run it, you make that version of events a little more familiar, and rehearsal is exactly for that.
So the question was never whether you should visualise, because you will. The only question is what you are going to put in front of yourself.
Why we rehearse the disaster
This isn’t weakness or pessimism. Running the disaster feels like preparation, diligent, as though imagining the humiliation enough times will somehow prepare you for it.
It doesn’t. By the time you walk into that room, you will have been through the terrible version twenty times and the ordinary version not once.
That is also why being told to stop worrying about it never helps. You cannot delete the film. Telling your mind not to picture something is a reliable way of picturing it. Instead, give it different material to work with.
What to put in front of yourself instead
Not the applause.
Picturing the outcome is the most common mistake and the least useful. The nodding, the handshake, the email the next morning. It is pleasant, and it changes nothing, because a result is not something you have to perform.
Picture the doing.
The moment you stand up. The walk to the front, which is always longer than you remember. Where your hands go while the room settles. The first sentence, delivered at the pace you actually want rather than the pace nerves will suggest. Looking at one person, finishing a thought, moving on.
Those are things you’ll actually have to do. Practising them is rehearsal; imagining the applause is daydreaming.
Put the friction back in
Here is the part that most advice gets wrong in the opposite direction.
Don’t picture it going perfectly. If you’ve only ever rehearsed a flawless version, the first little hiccup can throw you off, and something almost always does. Maybe your laptop acts up, someone arrives late, or you lose your train of thought a few minutes in.
So put those in deliberately. Not catastrophe, just friction. See yourself pausing, finding your place, and carrying on without drama.
What you are rehearsing there is not the mishap. It is your own recovery, and a presenter who has already recovered a few times in their head recovers far more easily in the room.
This is also an honest way to respond to the disaster film. You’re not pretending that nothing will go wrong; you’re practising how to stay steady when it does, which feels more genuine and is far more useful.
This is not the same as a pre-mortem
There is a version of imagining failure that is genuinely useful, and it is worth separating from the one above.
Running a pre-mortem for presentation anxiety is a deliberate exercise. You sit down, once, and ask what could go wrong: the technology, the hostile question, the person who has to leave early, and you decide in advance what you would do about each one. It has an output. You finish with a plan, and then you stop.
Rehearsing the disaster is none of those things. It is involuntary, it repeats, and it produces nothing. You feel the humiliation on a loop, and you are no better prepared at the end of it than you were at the start.
The test is simple. If it ends with something written down, it was planning. If it just ends with you feeling worse, you were running the film again.
Ten quiet minutes
You do not need an hour.
Find somewhere you won’t be disturbed. Close your eyes, breathe slowly, and count down from ten to one. Then work through it in order:
– Walking to the front and pausing before you speak
– Your opening sentence, at the pace you want
– Making eye contact with one person and holding it
– Something small going wrong, and you carrying on
– Taking a question you did not expect, and handling it
Do it more than once. The first attempt is usually vague and faintly embarrassing. By the third or fourth, it starts to feel familiar, and familiar is the entire point.
Start about a week out and do it every other day, then once more on the morning itself. If all you have is one evening, do it three times that evening. It is the repetition that does the work, not the length of each one.
What it won’t do
It will not make up for not knowing your material, and it will not rescue a presentation that has no point to make.
It will not remove nerves either. That is a separate subject, and if the nerves are the main thing standing in your way, I have written about what actually helps with presentation nerves.
What it will do is take some of the strangeness out of the experience before you get there. Much of what makes presenting hard is unfamiliarity: the room you have not stood in, the opening you have not made, the question you have not fielded.
You are going to rehearse one version of all that in your head regardless. You may as well choose which one.
If you would like some help with this:
– Book yourself onto a powerful public speaking course.
– Invest in some really good one to one public speaking coaching.
– Get yourself some excellent presentation skills training.
If this was useful, pass it on to somebody who has been running the wrong film all week.
