Richard Feynman was one of the greatest physicists of the twentieth century — Nobel laureate, Manhattan Project contributor, foundational theorist in quantum electrodynamics. He was also, famously, someone who couldn’t stop playing.
He played bongo drums. He cracked safes at Los Alamos for fun. He spent considerable time in strip clubs drawing portraits, which he considered a form of playful exploration. And at one point, in a period of what he described as creative exhaustion and burnout, he made a deliberate decision to stop trying to do important work and simply follow whatever amused him.
What amused him, at that particular moment, was watching a plate wobble as it was thrown in a university cafeteria. The wobble interested him. He started working out the mathematics of it, not because it was important — it clearly wasn’t, it was a wobbling plate — but because it was interesting. It was fun.
The mathematics of the wobbling plate led, eventually, to work on the equations of electron motion that became part of the research for which he won the Nobel Prize.
Ali Abdaal tells this story in Feel-Good Productivity, and it’s become one of the most useful frameworks I have for thinking about sustainable practice.
The Pressure Trap
There’s a version of practice that operates entirely under the sign of importance. I have to get better at this. I have to develop this skill. My performance in three months depends on mastering this. Every session is a debt being paid to a future performance.
This kind of practice is emotionally exhausting in a way that has nothing to do with physical effort. The weight of importance compresses every session. There’s no room for wandering, for following tangents, for doing the thing that’s interesting rather than the thing that’s most urgently necessary. Every moment of practice is accountable to the future performance, and anything that doesn’t directly serve that performance feels like waste.
I practiced like this for a period. Identified the specific things I needed to improve, designed structured sessions to address them, tracked progress against targets. Rigorous. Systematic. And after a while, I noticed I was dreading the hotel room sessions that I had previously looked forward to.
That’s the signal. When practice becomes something you’re doing to discharge an obligation rather than something you’re doing because you want to be doing it, the quality and the sustainability both decline. You can sustain obligation-based practice for a while. But not indefinitely. And the work you produce from it has a slightly effortful quality that audiences can sense.
What Feynman Discovered
Feynman’s insight — or rather, what Abdaal draws from it — is that following genuine curiosity and joy doesn’t lead away from important work. It often leads toward it, because the cognitive state that produces playful exploration also produces the unexpected connections and insights that genuine creative work requires.
When Feynman was playing with the plate, he wasn’t being irresponsible about his career. He was entering the cognitive state that his most productive work required. The plate was the door, and play was the key, and what was on the other side of the door happened to be significant physics.
The mechanism, as best we can describe it: playful exploration keeps the prefrontal cortex in a generative rather than evaluative mode. When you’re playing, you’re generating possibilities. When you’re working under pressure toward a specific outcome, you’re evaluating and selecting among possibilities you’ve already thought of. Generative mode produces more material. More unexpected connections. More of the kind of insight that turns a wobbling plate into a Nobel Prize.
What This Means in Hotel Rooms
The hotel room practice sessions that I’ve found most productive over the years are not the ones I planned most carefully. They’re the ones where I sat down without a specific agenda and started doing the thing that interested me right now.
Sometimes that’s working on a specific effect I’ve been struggling with. Sometimes it’s exploring an effect I have no plan to perform — something I found in a book that interested me conceptually, even if it’s not appropriate for my current repertoire. Sometimes it’s trying to understand a principle from a different angle than I’ve approached it before. Sometimes it’s just playing with a deck of cards with no particular direction, seeing what happens.
The planned sessions produce incremental improvement. The play sessions produce breakthroughs. Not always, not reliably, not on schedule. But the ratio of significant insights to session time is higher in the unstructured sessions than in the structured ones.
I think this is because in the structured sessions, I’m working within my existing model of what I’m trying to do. I’m improving within the space I’ve already defined. The play sessions allow me to stumble into spaces outside my defined model — spaces I wouldn’t have found if I’d been navigating deliberately toward a specific destination.
The Seinfeld Strategy and Its Limits
Abdaal also discusses the Seinfeld Strategy — the practice of maintaining a daily habit regardless of outcome quality, tracking the streak visually, never breaking the chain. This is an excellent system for building consistency, and I’ve used versions of it.
But the Feynman principle complicates the Seinfeld Strategy in a useful way. The Seinfeld Strategy says: show up every day. The Feynman principle says: show up every day and follow what’s alive.
These are compatible but distinct. Showing up every day without caring what you do when you get there is better than not showing up. But showing up every day and then doing the thing that’s genuinely interesting and fun, even if it’s not the thing you planned, is better still.
The combination: consistency of presence, flexibility of direction. I practice every day. What I practice on any given day is whatever has the most genuine energy for me right now.
The Professional Application
I carry the Feynman principle into my consulting work as well, and it’s been useful there too. The most interesting strategy problems I’ve encountered — the ones that produced the most genuinely creative frameworks and recommendations — have often come from following tangents that seemed peripheral.
A detail that didn’t fit the model. A pattern in a dataset that had nothing to do with the question we were trying to answer. A parallel from an industry that had no obvious connection to the client’s situation.
The pressure-based version of consulting work would dismiss these tangents as distractions from the deliverable. The playful version follows them, because something about them is interesting, and interesting things tend to lead somewhere.
Feynman wasn’t playing because he had nothing important to do. He was playing because play is the cognitive mode that produces the most important discoveries. The wobbling plate wasn’t a distraction from the physics. The wobbling plate was the physics, wearing different clothes.
The Sustainable Trajectory
The longer I practice magic — and I’m now years into this, with no plan to stop — the more I believe that the only truly sustainable practice is practice that generates its own motivation. Not practice sustained by discipline and obligation alone, but practice that you return to because you genuinely want to see what happens next.
This doesn’t mean abandoning structure or systematic development. Feynman was a rigorous physicist. The play was real, but it was play within a deep foundation of knowledge and capability. The plate would have meant nothing to someone without the mathematical framework to understand what the wobble implied.
The play works best when the foundation is solid. And the foundation gets built by a combination of structured development and the genuine curiosity that makes you want to build it in the first place.
When the curiosity flags — when practice starts feeling like obligation — that’s the signal to find the plate. To follow something that’s just interesting, without worrying about whether it’s useful. To trust that the Feynman principle is real: that following what’s alive tends to lead somewhere worth going.
