The best learning tool I have is a notes app on my phone. Not a journal, not a recording system, not a dedicated performance log — just the regular notes app, opened in the back seat of a taxi or a train, usually within an hour of finishing a show.
I start typing before the relief of being done has fully settled in, while the specific texture of the evening is still present in my memory. What happened. What worked. What didn’t. The thing someone said in the third row that I filed away and need to come back to. The moment the pacing broke down. The effect that landed differently than usual, and why.
Within forty-eight hours, most of this is gone. Not completely — I’ll remember the broad outlines of a show for weeks. But the specific texture of a moment, the particular quality of why something worked or didn’t, the fine grain of the experience — that fades fast. It’s not retrievable by trying to remember. It’s only captured if you write it down while it’s still warm.
This is the discipline that I think separates a performer who has done a hundred shows from a performer who has truly learned from a hundred shows.
The Relief Problem
Finishing a performance produces a specific physiological response. The stress of anticipation and execution dissipates, and what’s left is often a kind of pleasant exhaustion — the particular tiredness of having been fully present and then released. This feeling is real and it’s earned.
It’s also the enemy of learning.
Because that relief state produces an impulse toward closure. The show is done. The feedback was adequate or better. The audience applauded and no disaster occurred. The mind, exhausted by the effort of performing, suggests that we move on. We eat something. We have a drink. We talk about everything except the show. We go to sleep.
And in the morning, the show is a smooth summary in memory rather than a detailed map.
Most performers, in my observation, operate primarily from that smooth summary. They know, in general, which parts of their show work well and which parts need attention. What they don’t have is the granular, specific record of what exactly happened on Tuesday night and what it means — the kind of record that makes improvement precise rather than approximate.
What a Debrief Captures
The categories I write about immediately after a show are consistent, and they’ve developed over several years of doing this imperfectly and refining toward what’s actually useful.
First: what specifically worked, and what made it work. Not “the opener was good” — “the opener worked because the volunteer engagement in the first ninety seconds produced a genuine laugh that relaxed the room before I’d done anything technically complex.” The why matters more than the what, because the why is what’s transferable to other contexts.
Second: what specifically didn’t work, and what I think caused it. Same granularity. The tendency here is to be vague — “the middle section dragged a bit.” The useful version is: “the transition between the second and third effects has a structural gap — I’m filling it with words that aren’t doing anything, and the room’s attention dips in that window.” Vague diagnosis produces vague improvement. Specific diagnosis produces specific repair.
Third: surprises. Things that were different from expectation — effects that landed harder or softer than predicted, moments the audience did something I didn’t anticipate, lines that got an unexpected response. Surprises are data. They’re telling me something about the gap between what I thought was happening in my show and what’s actually happening.
Fourth: one thing to fix before the next performance. Not the full list of everything that needs work — just the one highest-priority item. This prevents the debrief from becoming a paralytic inventory of imperfections.
The Memory Decay Problem
What makes the timing critical is the rate at which performance memory degrades.
Studies on eyewitness testimony have documented how quickly memory reconstructs itself toward a more coherent, simplified narrative — the detail and texture of what actually happened gets replaced by a smoother version that’s easier to store. Performance memory operates similarly. The specific event gets normalized toward “show went well” or “show was rough,” losing the particular moments that tell you why.
Matthew Dicks, in his work on storytelling practice, describes his “Homework for Life” routine — the daily search for one story-worthy moment before it disappears. The logic is the same: by the time you try to recover specific memories a week later, they’ve already been processed into generic summaries. The practice is capturing the specific thing before the specific becomes general.
For performance debriefing, the same principle applies. Within an hour, the specific is still available. Within twenty-four hours, you’re already working from reconstruction. Within a week, you have the smooth summary.
What Happens to the Notes
The notes I write in the back of the taxi don’t stay in a taxi notes app. That would be an improvement over nothing but not much of a system.
At some point every few weeks — usually on a long train journey, which has become my preferred thinking environment — I go through the recent debrief notes and look for patterns. A specific effect appears in the “didn’t work” column three times in two weeks: that’s the effect that needs attention. A particular type of audience appears in the “worked better than expected” column consistently: there’s something about the show’s design that’s particularly well-suited to that context, and I should understand what it is.
The debrief is the raw material. The pattern review is where the learning becomes systematic.
The Show You Didn’t Debrief
There is a version of every show that is lost immediately after it ends, and that loss is one of the primary ways performers plateau.
The technical craft continues to develop — you do the effects more times, and the execution improves through repetition. But the subtler skills — reading rooms, adjusting to different audience types, understanding why your material works the way it does, developing the instincts that distinguish a seasoned performer from a competent one — these require reflection. They require the habit of asking, after every performance: what did this show teach me?
The show that teaches you nothing is the one you did fine, felt relief about, and moved on from. The relief is natural. Moving on without capturing what the show knew is a choice, and it’s one that compounds over time in the wrong direction.
The taxi ride home from a show is one of the most valuable learning environments I have. Unstructured, unremarkable, briefly quiet. And the show is still warm enough to tell the truth about itself.
