Flow is an optimal state of consciousness where you feel your best and perform your best, and it has preconditions Kotler calls triggers — roughly 22 known ones. Every trigger does one of three things: it drives norepinephrine into the brain, it drives dopamine into the brain, or it lowers cognitive load. All three routes converge on the same outcome, because flow follows focus: the state only shows up when all attention is on the here and now. Norepinephrine and dopamine are the brain's focusing drugs, pulling attention into the present. Lowering cognitive load works from the other side — the brain has a fixed energy budget, so stripping out competing demands liberates energy to spend on the task. The practical method is to stack triggers deliberately: protect 90-120 minute uninterrupted blocks, shut off all inputs, then layer in novelty, complexity, unpredictability, and immediate feedback.
Origin
Kotler built this from flow science dating to the 1880s, Csikszentmihalyi's global studies of optimal performance in the 1970s, and Robert Sapolsky's work at Stanford on novelty, complexity, and uncertainty driving dopamine. He originally believed flow was very hard to train and says he was wrong — the Flow Research Collective now trains it with everyone from US special forces to large corporations.
Core principles
- 01Flow follows focus — it only appears when all attention is in the here and now
- 02Every trigger works one of three ways: produce norepinephrine, produce dopamine, or lower cognitive load
- 03The brain runs a fixed energy budget, so removing distraction liberates energy for focus
- 04The only thing more powerful than neurochemistry is neurochemistry — beat the phone with a bigger reward
- 05Cognitive literacy makes performance repeatable rather than accidental
How to run it
- 1
Claim a 90-120 minute uninterrupted block
The research says you need 90 to 120 minutes of uninterrupted concentration to maximize flow. Kotler's rule for organizations: if you can't hang a sign on your door telling people to leave you alone while you're flowing, you can't do this work.
Pro tip For deeply creative work, schedule three to five hour luxurious stretches a couple of times a week.
Watch out Company policies that demand a reply within 15 minutes run directly against biological hardwiring — the brain does not multitask.

Shut everything down the night before
Lower cognitive load by killing the inputs before they can compete for attention. Kotler turns off Skype, internet, email, landline, cell phone, and lights when he leaves his office at the end of the day, so the next morning there is nothing to resist.
Pro tip Put the writing app in focus view so all you see are the words on the page.
Watch out Deciding to disconnect in the moment fails — the decision itself burns the energy you wanted for the task.

Attack the work at a fixed hour every day
Kotler gets up at four in the morning and writes from 4am to 8am, and has done so for thirty years. The fixed slot removes the daily negotiation about when to start.
Pro tip Research excursions mid-block are fine as long as you return to the same task — the constraint is task focus, not screen purity.
- 4
Inject novelty, complexity, and unpredictability
Sapolsky found the brain produces large quantities of dopamine whenever it encounters novelty, complexity, or uncertainty. Combine two of them and you get what he calls the magic of maybe — the thrum of possibility that reliably pulls attention forward.
Pro tip Travel is the everyday proof: novelty around every corner produces near-instant low-grade flow.
- 5
Engineer immediate feedback into the work
Immediate feedback is one of the best-validated triggers because it removes the wondering — you know how you're doing and can course-correct in real time. Professions with tight feedback loops produce the most flow; professions without them produce very little.
Pro tip Find a feedback buddy. Kotler pays a staff member to read his writing aloud to him a couple of times a week.
Watch out Everyone carries individual biases, so you have to learn what kind of feedback actually steers you toward flow. Kotler has found no diagnostic for it.
- 6
Run it as an experiment for two to three weeks
The phone's dopamine hit is a real addiction and willpower won't beat it — only a bigger reward loop will. Commit to the protocol for a fixed trial and judge it on the results at the end, when the successes from deep flow start outcompeting the pings.
Pro tip Learn to notice micro-flow — most people spend about 5% of their work life in flow and never notice it. Noticing is what lets you dial it up.
Watch out Expect it to feel weird and hard, especially if you have fear of missing out. Shutting down that much every day is abnormal to most people.
In the wild
Kotler shuts down every input at the end of the previous workday — Skype, internet, email, landline, cell phone, lights. He gets up at four in the morning, opens his computer in focus view so all he can see are the words on the page, and writes until eight. It's dark outside, there is no contact, nothing but words. He'll leave the writing to chase research and come back, but he stays on the task for roughly four hours straight, and has done this for thirty years. He calls it foundational to his performance.
→ Eight-plus bestselling books produced on a repeatable daily four-hour flow block sustained for three decades.
McKinsey ran a ten-year study of top business executives measuring their output in flow versus out of flow. Kotler uses it as the standing argument for why the protocol is worth the discomfort of disconnecting: the state isn't a nice-to-have mood, it's a step-function change in what the same person produces in the same hour.
→ Top executives were found to be five times more productive in flow than out of it — a 500% boost.
Common mistakes
Trying to willpower past the phone
The buzz in your pocket is a dopamine reward, the same chemical produced by cocaine, and no amount of resolve outlasts it. The only thing that replaces the craving is the bigger reward loop from deep flow states.
Disconnecting in the morning instead of the night before
Every input you leave live is cognitive load competing for a fixed energy budget. Kotler shuts everything down when he leaves the office so the block starts clean.
Assuming you can train the brain to multitask
Copious research shows the brain isn't built or wired for it. You can shift it a tiny bit over time, but uninterrupted concentration is how we're built and it's where you have to start.
Is it for you?
Best for
Knowledge workers, writers, coders, and executives whose output depends on long stretches of deep cognitive work.
Not ideal for
Reactive roles where the job is defined by responding to inbound requests within minutes.
