It is a quarter past eleven on a Thursday night. I am driving south on the A2 out of Vienna, heading home after a corporate event for an insurance company. The show went well. Standing ovation. Good energy in the room. The CEO shook my hand twice. People lingered afterward, which is always a better sign than polite applause followed by an immediate rush to the bar.
By every external measure, this was a success.
But I have learned something about success: it is perishable. The details of what happened tonight — the specific moments, the names, the reactions, the things that worked and the things that almost did not — are already starting to blur. By tomorrow morning, the sharp edges will have softened. By next week, I will remember that it went well, but I will not remember why. And that is a problem, because the why is where all the learning lives. I explored this further in The Director's Checklist I Use After Every Show.
So I pull into a gas station parking lot just past the Wiener Neustadt exit. I turn off the engine, open the notes app on my phone, and I start writing.
The Fifteen Minutes That Matter More Than the Show
The woman who volunteered for my mentalism piece was named Sabine. She worked in accounting. She was hesitant at first — I could see her looking at her colleagues for permission before she stood up. But once she was on stage, she committed completely. Good energy, genuine reactions. When the effect landed, she covered her mouth with both hands and turned to her table with wide eyes. That is the reaction you want. Not polite surprise. Genuine astonishment.
During my second piece, the energy dipped. I can pinpoint exactly when: it was the transition between the card revelation and the book test. Too much setup. Too many words. The audience's attention wandered for about thirty seconds, and I had to work to pull them back. That transition needs to be tighter. Maybe cut the preamble entirely and let the effect speak for itself.
The joke I made about the CEO's choice of word — that was spontaneous, and it landed harder than anything in my scripted material. The whole room erupted. I need to write that down verbatim before I forget the exact phrasing, because spontaneous moments that work are gifts. They do not come back on their own.
And the CEO herself — when I revealed the childhood phone number she had been thinking of, she went very still. Did not laugh. Did not gasp. Just went still, then quietly said, "That is not possible." That is a different kind of reaction than Sabine's, and both are valuable. The quiet ones sometimes run deeper.
All of this goes into my phone. Names, moments, energy shifts, things to keep, things to cut, things to explore. It takes about fifteen minutes. And those fifteen minutes are, I am increasingly convinced, more valuable than the sixty minutes I spent on stage.
Why I Started Doing This
I did not invent this practice. In my consulting life, after-action reviews are standard. The concept comes from the US military — after every operation, regardless of outcome, you sit down and systematically review what happened, what was planned, why the two diverged, and what should change next time. The format migrated into corporate strategy, project management, and eventually into every well-run organization I have worked with.
But it took me an embarrassingly long time to apply this to my performing life. For the first year or so of doing shows, I would drive home feeling either great or terrible, and by the next morning the feeling was all that remained. No details. No actionable insights. Just a vague emotional residue that told me nothing useful about what to actually change.
The shift happened when I was reading Oz Pearlman's Read Your Mind and encountered his description of a practice I recognized immediately from my other professional life. Oz writes everything down. After every show, every interaction, every corporate event. Names. Details. Reactions. He writes on the backs of business cards, in notebooks, on his phone — whatever is available. The medium does not matter. What matters is that he captures it while it is fresh.
What struck me was not just that he takes notes — plenty of performers probably do that — but what he does with them. Years later, he can recall details about people he met once. He remembers names, personal facts, preferences. When he encounters someone again, he can reference their previous interaction with a specificity that feels almost supernatural. People think he has an extraordinary memory. He does not. He has an extraordinary system.
Reading that was like watching someone in a different field arrive at the same conclusion I had seen validated a hundred times in consulting: the people who systematically capture and review their experiences outperform the people who rely on memory and instinct. Every time. Without exception.
My System
Here is what I record after every show, without exception. I do it in the car, or in a quiet corner before I leave the venue, or — if I am at a hotel — the moment I get back to the room. The rule is: before I do anything else. Before I check my phone. Before I call anyone. Before I decompress. The notes come first. I wrote about this in The Show That Teaches You Nothing Is the Show You Did Not Debrief.
First: what I performed, in order. This sounds obvious, but it matters because I do not always perform the same set. I adjust based on the audience, the room, the energy. If I do not record what I actually did, I cannot accurately assess what worked and what did not. The set list is the foundation.
Second: names and details of key audience members. The volunteer's name, what department they work in, anything personal they shared. The host's name and their role. Anyone who came up to me afterward and said something memorable. I am building a database of human connections, and this is the raw material.
Third: what worked better than expected. This is the most important category, and the one most performers skip. We are naturally drawn to analyzing our failures, but the unexpected successes are where the real growth lives. That spontaneous joke that killed? Write it down. That moment where you paused slightly longer than planned and the silence made the revelation hit harder? Write it down. These are the accidents that, if captured, become intentional tools.
Fourth: what needs to change. This is the obvious one. The transition that dragged. The line that fell flat. The moment where the audience's attention wavered. Be specific. "The second piece was not great" is useless. "The thirty-second preamble to the book test lost the room because I was explaining instead of performing" is actionable.
Fifth: any spontaneous moments worth keeping. This overlaps with the third category, but it is specifically about unscripted material — ad libs, audience interactions, unexpected situations that created magic of their own. These are the seeds of future scripted material, if you bother to plant them.
The Complement to Video Review
I have written before about the value of recording your performances and reviewing the footage. That practice is invaluable, and I still do it whenever possible. But the after-action review captures something the camera cannot.
The camera shows you what happened. The notes tell you what it felt like.
The camera captures your timing, your angles, your physical performance. It shows you whether your technique was clean, whether your blocking was effective, whether your gestures were natural. But it cannot tell you that the energy shifted during the second piece. It cannot tell you that Sabine from accounting was nervous but committed. It cannot tell you that the CEO's quiet "that is not possible" felt different from the usual gasps. It cannot tell you that the room felt like it was with you during the closer in a way it was not during the opener.
These subjective impressions are data. Not precise data, not measurable data, but data nonetheless. And if you do not capture them, they evaporate.
Together, the video review and the after-action notes create something close to a complete picture. The objective record and the subjective record. What happened and what it meant. I do not always have video — many corporate clients do not allow recording — but I always have my notes.
The Compounding Effect
The real payoff of this practice is not immediate. It compounds.
After ten shows, you have ten sets of notes. Patterns start to emerge. You notice that the same transition causes problems every time. You notice that a particular piece consistently generates stronger reactions than you expected. You notice that your energy tends to dip at the same point in every set — maybe you need to restructure the order.
After fifty shows, you have a body of evidence that transforms how you make decisions about your material. You are no longer guessing about what works. You know. You have documented proof, written in your own hand, from dozens of different audiences in dozens of different rooms.
And there is another payoff, one that I did not anticipate when I started: the notes become a record of your growth. I can go back to my earliest entries and see a performer I barely recognize. The things I was worried about then — basic timing, managing my nerves, remembering my script — are not even on my radar now. The things I worry about now — reading the room, calibrating energy, creating genuine connection — would not have occurred to the version of me who wrote those early notes. The notes are a map of my evolution, and reading them is both humbling and encouraging. This connects to what I found in The Six Cards I Keep in My Show Case: How Condensed Reference Sheets Work.
The Repeat Client Advantage
Here is the practical, unglamorous, utterly pragmatic reason this matters: repeat clients.
When a company books me for their annual event, and I return a year later already knowing that their CFO is named Thomas and he was the one who guessed wrong during the prediction piece last time, and that their head of marketing, Elena, was the one who received the impossible card, and that the best reaction came from the table near the left exit — when I walk in with that knowledge, something shifts.
The client feels known. They feel remembered. They feel like this is not just another gig for me, but a relationship. And they are right, because I have invested the time to make it one.
This is not a magic technique. This is not a mentalism principle. This is basic relationship management, the kind of thing that every good salesperson, every good consultant, every good doctor does. But performers, for some reason, often do not do it. They walk into a repeat booking with no memory of who was there last time, what happened, or what mattered. They start from zero every time.
I do not start from zero. I start from my notes.
When I mention Thomas's name in passing during the show, when I reference last year's event, when I acknowledge Elena with a knowing look — the audience does not know how I know these things. They might think I have an extraordinary memory. They might think I did extensive research. They might think it is part of the magic. The truth is simpler and less glamorous: I pulled into a gas station parking lot twelve months ago and spent fifteen minutes typing into my phone.
The Habit That Resists Formation
I will be honest: this practice is harder to maintain than it sounds. After a show, you are tired. You are either elated or deflated. You want to drive home, pour a glass of wine, and decompress. The last thing you want to do is sit in a parking lot cataloguing your evening like a field researcher.
But I have never once regretted doing it. And I have many times regretted not doing it — especially in the early days, before the habit was formed, when I would occasionally skip it and then find myself two days later unable to remember the name of the person who had the strongest reaction, unable to recall the exact wording of the line that got the biggest laugh, unable to reconstruct the sequence that caused the energy dip.
Those lost details are lost forever. Memory does not recover them. Memory rewrites them into something smoother, more flattering, less useful than what actually happened.
So the rule is absolute: notes first, everything else second. It does not matter how tired I am. It does not matter how well or how badly the show went. It does not matter whether I think there is anything worth recording. There is always something worth recording. I just might not know what it is until I read it back six months from now.
The Gas Station Epiphany
Back in the parking lot off the A2. My thumbs are typing faster than my thoughts. I have captured Sabine's name, the energy dip, the spontaneous joke, the CEO's quiet reaction. I have logged the set order, noted two transitions that need work, and flagged one moment where the audience leaned forward in a way I want to understand better.
It is twenty minutes past eleven. The whole process took twelve minutes.
Twelve minutes. That is less time than I spend warming up before a show. Less time than I spend setting up my props. Less time than I spend choosing what to wear. And yet these twelve minutes, repeated after every performance, have done more for my growth as a performer than any single practice session, any book, any workshop.
Because the show does not end when you leave the stage. The show ends when you have understood what happened on the stage. And understanding requires recording, reviewing, and reflecting — not just feeling good about the applause and moving on.
I start the engine, pull out of the parking lot, and merge back onto the motorway. The notes are saved. Tomorrow I will read them with fresh eyes and start making changes. The version of the show I performed tonight is already obsolete. The next version will be better.
That is the promise of the after-action review. Not perfection. Just relentless, incremental, documented improvement. Twelve minutes at a time.
