I remember the first time I looked up and it was 2 AM.
I was in a hotel room in what I think was Frankfurt, though the specific city is blurred now. I’d flown in that afternoon for a client meeting the following morning. I had a deck of cards I’d ordered from ellusionist.com a few weeks earlier, a tutorial on my laptop, and what I thought would be maybe an hour of casual experimenting before sleep.
Then it was 2 AM.
I hadn’t been practicing with discipline or intention. I’d been absorbed. There’s a difference. I hadn’t checked my phone, hadn’t thought about the meeting the next day, hadn’t noticed hunger or tiredness. My entire attention was somewhere in the gap between what my hands were trying to do and what the tutorial was showing me they should be doing.
I lay down genuinely confused about where the evening had gone.
The Flow Signature
Mihaly Csikszentmihalyi spent decades studying what he called optimal experience — the conditions under which human beings feel most alive, most capable, most themselves. He called the state “flow,” and he documented it across wildly different domains: surgeons, chess grandmasters, rock climbers, musicians, factory workers, mothers with infants.
The experience looked different across those contexts, but it had consistent signatures. Complete absorption. Loss of self-consciousness. A sense of effortlessness even while doing something difficult. And the one that I recognized immediately when I read it: time distortion. Specifically, the compression of time. Hours feel like minutes. The clock lies.
Flow happens, according to Csikszentmihalyi, at the intersection of two things: a challenge that matches and slightly exceeds your current skill level, and a task that gives you clear, immediate feedback about how you’re doing.
Both of those were present in that Frankfurt hotel room. The card work was genuinely beyond my ability — I was failing on most attempts. But the feedback was instant and concrete: either the sequence worked or it didn’t, and I could see exactly which. There was no ambiguity about whether I was improving. There was just the clear, immediate loop of attempt, result, adjustment.
That loop pulled me in and wouldn’t let go.
What Flow Is Actually Telling You
I want to make a distinction that I think is important.
Flow doesn’t just feel good. It’s informative. The fact that a particular activity produces it tells you something meaningful about the fit between you and that activity.
Not everything difficult and skill-demanding produces flow. I’ve done plenty of challenging work in my consulting career that was not absorbing in this way — work that required sustained effort and produced good results but where I was always aware of the time, always looking toward the end of the session. That work was valuable. It was not flow.
And not everything absorbing is flow, either. Anxiety is absorbing. Rumination is absorbing. Scrolling a phone is absorbing in a completely different and much more hollow way — time passes, but you don’t feel you’ve gone anywhere.
Flow is absorbing with a sense of momentum. You feel like you’re moving somewhere, building something, progressing even incrementally. The absorption serves the work rather than pulling you away from it.
When I look back at the range of things I’ve spent time on as an adult — consulting frameworks, organizational strategy, business development — the activities that reliably produced the time-compression were the ones that turned out to matter most to my development. Not universally. But there was a correlation.
Finding the thing that makes the clock lie is worth paying attention to as a signal.
The Sustained Attention Problem
Here’s why this matters practically: adults have scarce attention.
A professional life, relationships, responsibilities — these are all legitimate claims on finite cognitive and emotional energy. Learning a craft in adulthood means finding time and attention that aren’t already spoken for. This is hard under the best circumstances.
And when you’re working against fatigue, against the competing claims of other things you need to do, against the voice that says you should be more “productive” with this time — sustaining practice through willpower alone is exhausting and eventually unsustainable.
Flow changes this equation. When you’re in the absorbed state, you’re not fighting for attention. The activity is pulling you in rather than you pushing yourself into it. The time happens without you having to manage it.
This is one reason why finding the specific thing that produces flow for you — rather than practicing anything that seems like it should be practiced — is worth the time investment. The person who finds their version of that hotel-room experience will practice more hours over a year than the person grinding through material they’ve chosen for good reasons but that never quite captures them.
Sustained engagement beats disciplined effort. Not because discipline doesn’t matter — it does, especially in the early phases. But over the long arc of skill development, absorption is more renewable than willpower.
The Match Matters
One of the things Csikszentmihalyi found is that flow isn’t arbitrary. The activity has to be in the right zone of difficulty — not too easy, not too hard.
Too easy and there’s no engagement. You’re going through motions. Time doesn’t compress; it drags.
Too hard and there’s anxiety rather than absorption. The challenge is too far beyond the skill to produce momentum. You’re overwhelmed, not immersed.
The flow zone is where the challenge slightly exceeds your skill in a way that feels stretching rather than crushing. This is also why flow shifts as you improve: what was once in the flow zone becomes too easy, and you have to move to harder material to find the state again.
This is one of the more elegant aspects of the concept. If you’re seeking flow as a guide to where to work, it will naturally direct you to keep pushing the level of difficulty. Comfort produces boredom, not flow. The search for the absorbed state keeps you moving toward the edge.
In the hotel room that first night, the card work was genuinely beyond my ability. I was failing on most attempts. But the failure was informative and the improvement was perceptible — I was slightly better at the end of the evening than at the beginning, and I could feel the incremental progress. That combination is exactly the formula.
What I Found Later
One of the useful things about knowing what flow feels like is that you can use it to evaluate material.
When I’m deciding whether to invest serious practice time in a new piece, one of the questions I ask is whether practicing it produces absorption or just obligation. Does working on this pull me in? Does time start lying to me?
If yes, I’m more confident the investment will pay off. Not because flow is sufficient for performance quality — it’s not, and absorbed practice still requires deliberate design — but because absorption predicts the sustained engagement that’s required for mastery. You can’t shortcut the hours. The hours have to be there. And the hours come more reliably from absorption than from discipline.
If no — if working on a piece consistently feels like I’m grinding through a requirement — I take that as information. Maybe the piece isn’t the right one for me. Maybe it’s in the wrong zone of difficulty. Maybe there’s a different approach to the material that would be more engaging.
Not everything will produce flow. Some material needs to be learned for reasons other than absorption. But where I have a choice, I follow the clock-lying signal.
The Practical Invitation
If you’re reading this as someone who has a craft they’re developing — or thinking about developing — I want to offer the clock as a diagnostic tool.
Not as a test you grade yourself against, but as an observation to make. When does time compress for you? Not in passive entertainment — watching something absorbing doesn’t count. In active engagement, in doing rather than consuming. When does an hour of work turn out to have been two hours?
Whatever that activity is, it carries information about what might be worth pursuing at depth.
For me, it was a deck of cards in a hotel room at what turned out to be 2 AM. For someone else it might be something else entirely. The specific domain is less important than the signal.
Find the thing that makes the clock lie. Then take that signal seriously. It’s the closest thing I know to the nervous system saying: yes, this.
