WHEN YOU'RE BUILDING YOUR LIFE

13. Be Water, My Children

"You want to be yourself, idiosyncratic; the collective (school, rules, jobs, technology) wants you generic to the point of castration." —Nassim Nicholas Taleb

Dear Kids,

Leverage tells you where to apply your strength. But the deepest leverage of all — the note I want to end this stretch of letters on — is the ability to think for yourself. To stop inheriting your strategies and start choosing them.

You've probably heard Bruce Lee's famous line: be water, my friend. It's everywhere — motivational posters, movie trailers, the bottom of inspirational Instagram posts. I heard it a thousand times and thought I understood it. Something vague about flexibility. Going with the flow. Being adaptable. I was wrong about all of it.

A while back I listened to the actual recording of Bruce Lee speaking — not the cleaned-up quotes, but his real words, talking about martial arts and fighting styles. And the thing clicked into a completely different shape. Be water isn't soft. It isn't passive. It isn't zen wisdom about going limp in the current. It is one of the most radical instructions for how to think that I've ever encountered. It applies to fighting, to careers, to relationships, to nearly every decision you'll make.

I want to spend this letter on what he actually meant.

The trap of inherited style

Here's what Bruce Lee noticed that other martial artists hadn't. Most fighters were trapped in their own styles. The Wing Chun practitioner did only Wing Chun. The boxer did only boxing. The karate master did only karate. They weren't choosing those limitations — they were inheriting them. They did what their teacher did, who did what their teacher did, going back generations. None of them had stopped to ask whether the technique they were practicing actually worked in a real fight against a different style.

Sound familiar, kids?

It's how most people live their entire lives. They go to college because that's what you do. They pursue certain careers because that's what successful people pursue. They structure their days, their relationships, and their ambitions around inherited patterns they've never paused to question.

Bruce Lee's insight wasn't be flexible. It was something much sharper: stop accepting things just because they were handed to you. Understand WHY each technique exists. Question everything. Then build your own way based on what actually works.

That, kids, is the whole thing.

What Bruce Lee was reaching for — and what I only really understood after reading the Tao Te Ching in Beijing — is far older than him. Lao Tzu writes that the softest things in the world overcome the hardest. Water is the softest of all, and yet it wears away stone. I read the David Hinton translation slowly, a few verses a night in my dorm room my first winter in Beijing, and the chapter on water rearranged something. Lao Tzu wasn't describing surrender. He was describing a strategy. Water always seeks the low ground — the place no one is competing for — and from that low ground it patiently shapes the high ground. It doesn't fight gravity, it uses it. It doesn't break against the rock, it goes around the rock until the rock isn't there anymore. Be water isn't a martial arts quote that happens to sound Eastern. It's a paraphrase, twenty-five centuries later, of one of the oldest pieces of strategic advice in the world. Knowing the original source made me trust the lesson differently.

The five levels of questioning

Bruce Lee described a five-level framework for learning that I think about constantly. Most people never make it past the first level. They spend their entire lives there. Once you see all five, you can't unsee them.

Level 1: How do you do X?

Surface-level, copy-and-paste learning. You mimic the technique. You imitate the form. You execute the action.

In martial arts: How do I throw this punch? In life: How do I get into college? How do I get promoted? How do I find a partner?

You're learning the moves. Following the steps. Copying what others do. The vast majority of people stop here, forever, executing a series of how-to instructions they've collected from school and parents and the internet, never asking what any of it is for.

Level 2: Why do you do X this way?

This is the beginning of understanding.

Why this movement? Why this angle? Why this sequence? In martial arts: Why do we pivot on this foot? In life: Why do we go to college? Why do companies hire this way? Why do relationships follow these patterns?

The second you start asking why, you stop being a follower and start being a thinker. Most people avoid this question because it sometimes reveals that the things they're doing make no real sense — and once you've seen that, you can't pretend you haven't.

Level 3: What principles make X work?

Now you go deeper. Timing. Leverage. Structure. Economy of motion. These universal principles explain why the technique works in the first place. You're not learning moves anymore. You're learning laws.

In martial arts: Power comes from the ground up through the kinetic chain. In life: Trust compounds through small consistent actions. Networks scale exponentially, not linearly. Self-trust grows from keeping promises in private.

Once you understand the principles, you can create your own solutions. This is where Bruce began dismantling rigid kung fu forms. This is where you begin dismantling rigid life forms.

Level 4: When does X fail?

This is the level almost no one reaches.

When does this technique fail? Against what opponent? In what environment? Under what conditions? In martial arts: This technique fails against a taller opponent. This stance is vulnerable to leg kicks. In life: This career path fails if AI automates it. This relationship pattern fails when real stress arrives. This investment strategy fails in high inflation.

This is radical honesty — the Ray Dalio level. It's acknowledging reality even when it contradicts tradition. Clinging to a technique that fails in real combat is deadly. Clinging to a belief that fails in real life is equally deadly. And yet most people would rather be wrong with the crowd than right alone.

Level 5: How do I adapt in real time?

This is mastery. You identify alternatives. Adaptations. Contingencies. You modify, evolve, abandon when the situation calls for it. You become fluid and formless.

In martial arts: If he's taller, I change my distance. If he's stronger, I use his force. If this doesn't work, I instantly switch. In life: If this industry is dying, I transfer my skills. If this approach isn't working, I pivot. If the world changes, I change with it.

This is where be water finally emerges. Adapt to the circumstance. Flow around obstacles. Crash when necessary. Take the shape required by reality, not tradition.

The tragedy of level-one living

Here's what breaks my heart, kids. I see brilliant people stuck at level one everywhere. They know how to do their job but have never asked why their job exists. They know how to maintain a relationship but never questioned why they follow certain patterns. They know how to make money but never examined what principles actually produce wealth. They never reach level four to ask when their strategies will break. They never reach level five to develop the fluidity to change.

They're masters of execution and strangers to understanding. They've been trained to never question — only to perfect the execution of what was handed down.

Some of the smartest people I know at McKinsey were stuck at level one in their own lives — extraordinary executors of a script someone else had written. They could solve a client problem in 48 hours. They couldn't tell you why they were working there in the first place. The script had been so thoroughly rewarded for so long that the question had stopped being askable.

What Bruce Lee shared with Munger and Musk

What Bruce Lee was describing, Charlie Munger calls first principles thinking. Ray Dalio calls it radical transparency. Elon Musk uses it to redesign rockets. They're all describing the same move.

Instead of reasoning by analogy — we do it this way because that's how it's done — reason from first principles. Break the situation down to its fundamental truths. Build up from there.

Bruce Lee did this with fighting:

What is the shortest distance between two points? A straight line. So the direct punch is often most efficient.

What generates the most power? The whole body in motion. So use your entire body, not just your arm.

What works against a taller opponent? Different things than what works against a shorter one. So know your opponent before you commit to a style.

Simple truths. But revolutionary when everyone else is stuck in dogma.

Where it shows up in your life

Every major decision you'll face has its own orthodoxy — its own "martial art style" that people follow blindly without ever quite questioning why.

Career. Go to a good school. Get good grades. Work at a prestigious company. Climb the ladder. But why? What's the actual goal? Financial security? Impact? Freedom? Once you name the real objective, you might find paths that look nothing like the ladder, and that everyone else is ignoring because they don't fit the inherited shape.

Relationships. Date this kind of person. Get married by this age. Have this many kids. But why? What actually creates a fulfilling relationship for you? What structure supports your values, not the inherited template?

Success. Make this much money. Live in this neighborhood. Drive this car. But why? What does success actually mean to you once you strip away everyone else's definitions, including the ones your parents quietly installed in you before you were old enough to question them?

This isn't about rejecting tradition for the sake of it. Tradition often encodes hard-won knowledge. The point is to know why you're keeping a tradition — and to keep it because it works, not because it's familiar.

The water metaphor, finally understood

So when Bruce Lee says be water, he isn't saying be passive or go with the flow. He's saying:

Understand the container. Know the actual constraints and context you're operating in, not the imaginary ones everyone assumes.

Adapt your form. Don't be wedded to one approach. If the situation calls for ice, freeze. If it calls for steam, evaporate. If it calls for a current, flow.

Maintain your essence. Water is always H₂O, regardless of form. You can change methods without losing your principles.

Find the path of natural effectiveness. Water doesn't try to go through the rock. It goes around. It doesn't struggle against gravity. It uses it. That isn't weakness. It's intelligence about where to put force and where not to.

A counterargument I take seriously

The honest pushback on this is that questioning everything can become its own pathology. There's a kind of person who reads about first principles and decides nothing handed to them is worth keeping — who rejects tradition as a default move, and ends up rebuilding bad versions of things that were already solved.

You don't have to throw everything away, kids. Most traditions encode something real. The point of the five levels isn't to reject what you've been given. It's to know why you're keeping it.

Keep what works. Modify what mostly works. Abandon what doesn't. And know which is which, because you actually thought about it — not because someone told you so, and not because contrarianism was in fashion the year you read about it.

The mature version of be water isn't I reject all forms. It's I have considered the form, and I keep what helps me reach my goal, and I drop what doesn't.

Have your H₂O

Being water doesn't mean having no principles. Water has properties. It always seeks its level. It always takes the path of least resistance toward its goal. It's patient enough to carve canyons and powerful enough to destroy mountains.

Have your core principles. Let those be your H₂O — unchangeable, non-negotiable. The four or five things you won't compromise on no matter what container life pours you into. Mine, I think, are: tell the truth. Take care of the people who took care of me. Don't trade my long-term health, mental or physical, for any short-term reward. Make things. Stay curious.

But everything else — your methods, your strategies, your tactics, your form? Let those be as fluid as the situation requires. You'll know you've internalized this when you stop asking what should I do? and start asking what makes sense here?

You'll know you've become water when you can enter any situation — any challenge, any opportunity — and find your form without losing your essence. You'll know you've mastered it when someone asks what's your style? and you can honestly answer: whatever the moment requires.

What to do this week

If I had to give you one practical move out of this whole letter, kiddos, it would be this. Pick one thing you do regularly — a habit, a routine, a default response — and ask the five questions about it. How do I do this? Why this way? What principle is underneath it? When does it fail? How would I adapt if it did?

You'll find, I think, that some of what you do is right for reasons you couldn't articulate until you tried — keep those, now with confidence. Some of it was someone else's choice that you inherited without consenting to. Modify those. And some of it has no good reason at all, and you've been doing it for years out of pure inertia. Drop those, today.

Don't inherit dogma. Inherit the ability to think.

Don't accept styles. Accept what works.

Don't be rigid. Be water.

And when someone tries to hand you a predetermined path — a style, a this is just how it's done — remember Bruce Lee in that recording, calmly explaining that the best fighters aren't the ones who master a style. They're the ones who transcend style itself.

Be water, my children.

But first, understand why.

Love,

Dad
