🧠 Insights You Won’t Forget
Today's insights are inspired by a recent episode of Founders on Jiro Ono (the 3 Michelin Star sushi restaurant in the subway)
Mastery Through Obsession
Jiro embodies the shokunin ethos: total immersion in one craft, relentless self-criticism, and never-ending pursuit of improvement. His mantra is simple: “Once you decide on your occupation, you must immerse yourself in your work… dedicate your life to mastering your skill”.
Simplicity as Ultimate Advantage
Jiro’s sushi is minimal, only fish and rice, yet globally revered. His philosophy: “A novice is easily spotted because they do too much. A master uses the fewest resources required to fulfill their intention.” In business, clarity and reduction often unlock depth.
Details Define Excellence
Jiro limits the number of details to perfect, then makes each flawless. From rice temperature to timing (customers have 10 seconds to eat each bite), every element is calibrated. This echoes Walt Disney’s warning: “If we lose the details, we lose everything”.
Relentless Iteration Over Decades
From massaging octopus longer to boiling shrimp only at the moment of serving, Jiro constantly tests refinements. He embodies kaizen, thousands of micro-experiments over decades create world-class output.
Build on Competence, Not Comfort
Scarcity in his childhood made Jiro see competence as the only safe harbor. A skill that cannot be taken from you ensures survival and prosperity. Comfort-seeking (“easy job, free time, money”) weakens long-term resilience.
Specialization Compounds Trust
Just as Jiro relies on a tuna dealer who buys only the best tuna, each vendor is the best at one ingredient. This mirrors Mr. Beast’s team structure, world-class focus on one narrow area per person. Specialization plus trust builds moats.
Apprenticeship as a Filter
Jiro trains apprentices for 10 years before letting them cook eggs. One recalls making 200 rejected omelets before passing. Long apprenticeships filter out the uncommitted and ensure mastery, proving excellence cannot be rushed.
Inner Scorecard > Outer Recognition
Jiro skipped ceremonies, returned from awards straight to work, and measured success by his own standards of taste and craft. Like Sam Zemurray, he prioritized the work over the honors. Sustainable greatness requires internal benchmarks.
Recall from last week
Mortality as a Decision-Making Tool
Jobs used the inevitability of death as a filter for choices: “If today were the last day of my life, would I want to do what I am about to do today?” This helped him cut through noise and focus on meaningful work.
Differentiation is Survival
Jobs saw Apple’s darkest days as the consequence of lost differentiation. His cure: relentless innovation and focus. Bezos would later echo this truth—differentiation equals survival.
💡 Eko Worth Remembering
“When we have good tuna, I feel great. When I’m making sushi, I feel victorious.”
⚡ Active Recall – Test Yourself
Question: If simplicity and relentless refinement were applied to your business or craft, what details would you strip away, and which few would you perfect to create unmatched value?
🛤️ Off the Record
Take me back to the night we met. I’m sure that is what Jiro thinks when he reflects on his chosen shokunin. There is something beautiful in that. Dedicating your life to one thing and one thing only.
The pursuit of master of your craft. While people do not take things that seriously anymore, maybe we should. Or at least realize what it means when we say ‘yes’. A core part of your character is shown in weather or not you follow through on your word.
In respect to Jiro’s life choices I wanted to reflect on and choose some maxims on how I want to live my life. Here is what I came up with (in no particular order):
Treat your body like a temple.
No man is an island.
Treat people with kindness, even if they don’t return it.
Learn as if you were to live forever.
Simplicity is the ultimate sophistication.
Gratitude turns what we have into enough.
Courage is not the absence of fear, but action in-spite of it.
Answer:
Identify the core offering, remove unnecessary complexity, and elevate a small set of critical details to flawless execution, like Jiro does with fish, rice, and timing.
