Elon Musk built rockets and cars that people swore were impossible. Ask him how, and he’ll tell you he uses first principles thinking. Strip away assumptions. Rebuild from raw truth. Ignore how things have “always been done.”
There’s just one problem with that story.
The Man Who Actually Invented It
Musk didn’t invent the method of first principles thinking. Nobody alive did. Aristotle was reasoning from first principles 2,300 years ago.
What Richard Feynman invented, decades before Musk, is the test that tells you whether you’ve actually done it. And he used it in a far more dangerous way.
Feynman was a Nobel Prize-winning physicist whose work sits inside the laser, the microchip, and the phone in your pocket right now. But his real genius was simpler than any of that.
He refused to accept any idea he couldn’t explain in plain words, and that habit let him see what rooms full of experts kept missing.
It wasn’t a party trick. When NASA buried the Challenger disaster under layers of jargon and blame, Feynman walked onto live television, dropped a rubber seal into a glass of ice water, and showed the truth in about ten seconds. No slides. No acronyms. A piece of rubber in cold water, and the whole explanation was over.
That same discipline is the exact line between businesses people understand, and those people ignore.
Musk used first principles to solve engineering problems. Feynman used it to catch himself not understanding what he was sure he understood. His rule was simple: if you can’t explain something in plain terms, you don’t actually understand it.
But here is the part everyone miscopies.
Feynman’s rule was not “make complicated things simple.” That’s the bumper-sticker version. His real point cuts deeper: if you cannot make it simple, you probably haven’t found the fundamental truth yet.
Feynman would sit with a blank piece of paper and try to explain any concept as if the person listening had never heard of it. The moment he got stuck wasn’t a communication failure. It was evidence. Evidence that his understanding had a hole in it, and the hole had been hiding behind a fancy phrase the whole time.
The jargon was never the explanation. It was the mask over the gap.
This should terrify every founder reading this right now.
Your Jargon is a Trillion-dollar Confession
Sit in enough strategy meetings, and you’ll see the same decks over and over. Bold claims dressed up in words like synergy, ecosystem, best-in-class solution, and value proposition. The room nods. Everyone feels smart. Nobody asks a simple question.
Ask that same executive to explain their brand to a twelve-year-old. Watch the silence.
That silence isn’t a communication problem. It’s Feynman’s stuck point. It’s proof that underneath the deck, where the real idea was supposed to be, nothing but expensive sentences is standing in for one.
Complexity is where weak differentiation goes to hide.
When you cannot isolate the fundamental truth of your brand, you compensate with vocabulary. You pile on syllables, frameworks, and buzzwords, hoping nobody looks under the hood.
Naval Ravikant made the exact same observation about founders. Excessive terminology, he says, usually means you know the names of things but not their underlying relationships. Knowing a word is not the same as knowing what it connects to. And that is the difference between repeating something and understanding it.
Put it to the test.
Musk asks, “What is a rocket actually made of?”
Feynman asks, “What do we actually know?”
Naval asks, “Can you derive it from the fundamentals?”
The branding version is simpler and harder: “What is the one thing about this company that stays true after you strip away every adjective, claim, cliché, and category convention?”
That’s the real discipline. Not plain language for its own sake. First-principles differentiation.
I’ve been doing this for over four decades. The brands that got this right have generated more than $9.8 billion. The ones that didn’t lose an amount nobody will ever calculate, because you can’t invoice for the sale you never got.
The brands that won had one thing in common. I could explain every single one of them in a single sentence that a child could hand back to me.
Alex Hormozi, who has spent his career teaching founders to sell, lands the identical rule in marketing language: you will never be clever enough to replace being clear. People think the job is to be clever. The job is to be clear. Same principle, a different room, the same lesson. He spends an hour on it here, and it’s worth the hour.
The Twelve-year-old Test
KnowBe4, whose software trains employees not to fall for phishing: “Human error. Conquered.” I worked with Stu Sjouwerman creating the name KnowBe4 and their differentiator: Human error, Conquered. The company went on to a $4.6 billion valuation.
Menomonie, Wisconsin, a city that needed to differentiate itself from surrounding cities and destinations: “Right in the middle of everywhere.” Tourism rose 500% in a single year, with no increase in marketing spend.
A nutrition bar with five clean, pronounceable ingredients: “Delicious. Nutritious. Nothing suspicious.”
A gourmet jerky line: “Nature’s original protein bar.”
Not one comma of committee-approved word salad. Just an idea simple enough to survive contact with a child.
That’s your test. It isn’t complicated, which is the entire point.
Explain what makes your brand different. Out loud. To someone who has never heard of your company. The second you reach for a buzzword, you’ve found your stuck point. You’ve found the exact place where you don’t yet know what actually makes you different.
Most founders treat that moment as a writing problem. It isn’t. It’s an understanding problem, and you can’t hire your way past it. An agency will just dress the confusion in nicer fonts.
Never Learn for One
Here’s the discipline I teach, and it’s the one that fixes this.
Never learn for one. Always learn for two.
When you study something, don’t study it to know it. Study it so you can hand it to someone else and watch them pick it up, understand it, think with it, and successfully use it. If you can’t do that, you don’t have it yet. You have some jargon sitting there instead of a clearly understandable idea.
The moment you learn for two, your depth of understanding multiplies. You stop collecting terms and start seeing how the parts connect, because teaching won’t let you skip the connections.
I built my Brand Intervention masterclass on that principle. The 100 entrepreneurs I put through that 9-week program generated over $512 million in new business.
Feynman did it with a blank piece of paper. I do it with entrepreneurs and founders. Same rule.
And clarity is only half the job. A sentence a child understands can still belong to your competitor word for word. That’s a different test, and I just ran it on Honda.
Nobody Does This Alone
Musk didn’t do it alone. Feynman didn’t either.
The blank sheet of paper only works because somebody is on the other side of it. That’s the entire mechanism. You need a person who has never heard your explanation to show you where it falls apart. The lone genius is a story people tell afterward, and anyone selling it to you is lying.
It’s a role I’ve filled for my clients for decades.
Never learn for one. Always learn for two. That habit is the whole reason a second pair of eyes is worth anything: I’m not there to know your business, I’m there to hand it back to you in words you can use.
If you tried to say your sentence out loud and reached for a buzzword, you found it. Feynman’s stuck point. Yours.
That’s not a failure. It tells you the exact place where you don’t yet know what makes your company different, and no amount of rewriting gets you past it, because it was never a writing problem.
So here’s my invite: a free 30-minute Stuck Point Session.
I won’t workshop taglines with you. We go straight at the thing underneath the jargon: the truth about your business that a competitor couldn’t use if they tried. You’ll leave with it in plain words, short enough that a twelve-year-old could hand it back to you.
Then you’ll be able to hand it to your team. Which, as you now know, is the only proof you actually have it.
Why free? Think of it as a virtual “let’s grab a coffee.”
Because you’ve been explaining your business the same way for so long that you can no longer hear what’s missing from it. Thirty minutes with someone who has never heard it before fixes that faster than a year of internal meetings.
The fundamental truth about your company is already in there. Somebody just voted it down for being too simple.
