Water

Musashi’s Water Book is about the swordsman’s mind and body taking the shape demanded by the moment, rather than forcing a fixed form onto every situation. Water has no shape of its own. It becomes the shape of whatever it’s poured into, and that’s precisely what makes it dangerous as a fighting principle — an opponent expecting rigidity finds none to exploit.

Content strategy has the same problem rigidity does, and I think it’s the most common failure mode after the technical foundation is actually sound.

The same knowledge, asked for differently

Here’s the thing that took me a while to actually internalize: the underlying expertise doesn’t change, but the shape it needs to arrive in changes constantly, depending on who’s asking and how.

A person typing a fragment into a search bar — three or four words, no punctuation — is signaling something different than someone typing a full, conversational question into an AI assistant. The search-bar user has already done some translation work themselves; they’ve compressed a need into keywords and expect to do the rest of the interpretive work on the results page. The person talking to an AI system is often mid-thought, sometimes uncertain of the right vocabulary, and expects the system to meet them somewhere closer to their actual, messier question.

Both of them might be trying to solve the same underlying problem. But content built to serve one of them well can completely fail the other. A dense, keyword-optimized page built for the search-bar user can read as evasive or padded to someone who wants a direct, synthesized answer. A conversational, exploratory piece built for an AI-assistant user can read as thin or unstructured to a search engine trying to match it against a specific query.

Rigid content — the same page, the same explainer, deployed identically regardless of who’s arriving and how — is technique with no water in it. It has one shape, and it only fits the situations that happen to match that shape.

Where rigidity actually shows up

A few patterns I keep noticing, all versions of the same underlying inflexibility:

One format for every intent. A company writes a single comprehensive guide on a topic and expects it to serve someone doing quick research, someone deep in technical evaluation, and someone just trying to confirm a definition — all at once. It usually serves none of them particularly well, because those are three different shapes of need wearing the same topic.

Assuming yesterday’s format wins tomorrow’s query. The tactics that worked for ranking in a traditional search results page — a certain keyword density, a certain structure, a certain length — don’t automatically transfer to being selected and synthesized by an AI system pulling together an answer from multiple sources. Treating both as the same target is treating water as if it had a fixed shape.

Writing to impress rather than to fit. Content optimized to look authoritative — dense, jargon-heavy, comprehensive for its own sake — often fits the writer’s sense of expertise better than it fits the actual shape of the question being asked. Water isn’t about performing flexibility. It’s about actually reshaping around what’s in front of you, even when that means being shorter, plainer, or less impressive-looking than you’d prefer.

Reusing an old answer for a subtly new question. Categories evolve. The question “what is GEO” asked eighteen months into the term’s existence carries different assumptions than the same three words asked when the acronym was brand new. Content that hasn’t been revisited answers the old version of the question, politely missing the one actually being asked now.

Adaptability isn’t the same as inconsistency

It’s worth separating Water from its opposite failure mode, because they can look similar from a distance. Water isn’t about having no position, or endlessly reshaping your actual views to please whoever’s asking. Musashi wasn’t describing a swordsman with no training or center — he was describing one whose trained technique could still move fluidly rather than freezing into a single fixed posture under pressure.

The expertise itself should be stable. What flexes is the container it’s delivered in — the length, the framing, the entry point, the level of assumed context. A cybersecurity buyer researching a term for the first time and a peer debating its nuance on LinkedIn can be served by the same underlying knowledge, expressed in genuinely different shapes, without either version being less honest than the other.

Practically, what this asks of you

Water asks for something uncomfortable in a content operation built around efficiency: it asks you to produce more than one shape of the same idea, deliberately, rather than writing once and distributing everywhere unchanged.

That might mean the same core research becomes a tightly scoped answer built to directly satisfy a specific, narrow query, and separately becomes a longer exploratory piece built to be useful to someone still forming their question. It might mean revisiting older content not to correct an error but because the shape of the question it was answering has quietly shifted underneath it. It might mean noticing that a piece performing well in traditional search and a piece getting cited by AI systems are, structurally, not the same piece at all — and building for both on purpose rather than assuming one format serves both audiences by accident.

None of this is more work in the sense of doing more research. It’s more work in the sense of refusing to let one draft stand in for every situation it might be asked to serve.

Water doesn’t resist. It fits.

The martial version of this principle is about not meeting force with equal, opposite rigidity — flowing around resistance rather than colliding with it head-on. The content version is similar: don’t force every question into the shape of the content you’d already prefer to have written. Let the question determine the shape, and bring the same underlying expertise to however many shapes that turns out to require.

Earth determines whether you’re allowed into the contest at all. Water determines whether, once you’re in it, you actually fit the situation you’re in — rather than being technically present but practically irrelevant to the specific question being asked.
