The Green-and-Growing Filter: Who to Trust for Business Advice

Most bad martial arts business advice doesn’t come from bad people — it comes from people who never ran a genuinely successful school, or who did years ago and have since forgotten what actually worked. Before you take advice on building a million-dollar school, run it through a simple filter: has this person done it recently, did they do it themselves, and do they actually remember what they did?

Why I keep warning owners about the advice they’re absorbing

As CEO of NAPMA and Publisher of Martial Arts Professional magazine, I spend a huge amount of my time behind the scenes advising owners of half-million-dollar, million-dollar, and multi-million-dollar school operations — the top 1% of the industry, the ones actually generating six-figure and seven-figure incomes from their schools. Almost none of them started at that level. What I want to flag for you is something I see constantly at every level below that: a cacophony of voices in this industry, many of them charismatic, likable, and genuinely sincere, giving advice that is nonetheless deeply unreliable. Sincerity is not the same thing as competence, and charisma is not the same thing as a working system.

I break the unreliable advice-givers into a few recurring categories, and once you can spot them, you’ll see them everywhere. First, there are people who never actually owned a school of their own. Second, there are people who owned a school, but it was never particularly successful — maybe a five out of ten by their own peer group’s standard — and having done a bit better than the people immediately around them, they concluded that qualified them to teach everyone else. Third, and this is the trickiest category, are people who owned a genuinely successful school years ago, got frustrated, burned out, and walked away — and are now teaching what they wish they’d known back then, rather than what they actually did. That distinction matters enormously, because memory reshapes itself over time. People start teaching an idealized, retrospective version of their career instead of the messy reality of what actually worked.

The Green-and-Growing Filter

There’s a line I’ve always liked from Ray Kroc, the man who built McDonald’s into the organization it became (he didn’t found it — the McDonald brothers did — but he’s the one who scaled it into what we know today): “You’re either green and growing, or you’re ripe and rotting.” I use that line constantly with owners because it captures exactly what separates a school that’s genuinely on track to seven figures from one that’s quietly declining while its owner insists nothing has changed.

Out of that idea, I built what I call the Green-and-Growing Filter — a short set of questions to run any advice, and any advisor, through before you let it shape your business. It has five parts.

• Advisor screening: did they actually own and run a school themselves, and was it genuinely successful — not just better than their immediate peers?
• Recency check: are they teaching what’s working now, or what worked when they last actively ran a school?
• Memory check: are they teaching what they actually did, or an idealized, retrospective version of what they wish they’d done?
• Top-tier benchmarking: are you modeling the top 1–10% of the industry, or the middle of the pack?
• Adaptation habit: do they actively look for what’s changing — new channels, new tools, new behavior — or defend a fixed method regardless of results?

Advisor screening: have they actually done it?

I’ve watched genuinely charismatic, engaging school owners with some real financial success discover they cannot transfer what they did to anyone else, because what they built wasn’t a system — it was a personality. Think about it the way you’d think about sports: a legendary quarterback doesn’t automatically become a legendary coach. Very few elite athletes become elite coaches, because playing the game and teaching the game draw on almost entirely different skill sets. The same split shows up constantly in this industry. Someone can be a magnetic presence on the floor — the kind of instructor who can do the jump splits, run an electric class, have kids and parents leaving thrilled every single time — and still have no idea how to teach another owner to replicate those results without that exact personality standing in the room. If the “system” only works when a specific individual is present, it isn’t a system. It’s charisma, and charisma doesn’t scale.

Recency check: what worked then versus what works now

Every era of this industry has had its dominant lead-generation channel, and every one of those channels eventually faded. I’ve personally taught seminars on maximizing directory advertising back when that was the primary way people found a school, then watched that entire channel become close to irrelevant as search and digital advertising took over — and I’ve watched the digital landscape itself keep shifting since, as new platforms rise and older ones fade in effectiveness. The lesson isn’t which specific platform matters this year. The lesson is that the primary channel is always changing, and an advisor who’s still teaching the channel that worked for them a decade or two ago — without having adapted since — is teaching you history, not strategy. The Marketing growth hub covers how to keep your lead-generation approach current instead of frozen in whatever worked last decade.

This is exactly the trap that catches otherwise capable owners. I’ve talked with plenty of longtime, objectively successful owners — doing real numbers, netting real profit — who had quietly stopped adapting and didn’t see it. They’d tell me, “Three years ago we were doing a lot better, but everything’s harder now — it’s the economy, it’s the market.” Sometimes that’s partly true. But often what actually happened is they never adjusted to how people search for, evaluate, and choose a school today, and they were substantially under-maximizing their own results without realizing it — running at $40,000 a month while genuinely capable of $80,000, simply because their marketing and systems hadn’t moved forward while everything around them had.

What makes this trap so dangerous is that it doesn’t announce itself with a collapsing bank balance — it announces itself with a plateau that feels like stability. I’ve reviewed the books of owners doing what looks, from the outside, like real success: gross revenue in the mid-to-high six figures. But look closer and you’ll sometimes find a school grossing around $30,000 a month and netting closer to $15,000, or a school grossing $75,000 a month and netting only 10–20% after expenses. On paper that owner is “successful.” In practice, they’re often working harder than a much smaller school for a comparable or worse net result, simply because their cost structure, staffing, or lead-generation efficiency never got modernized. Ripe-and-rotting rarely looks like failure from the outside. It looks like a plateau with a straight face, and the only way to catch it is to actually track your net margin over time instead of just watching the top-line number.

Memory check: what they did versus what they wish they’d done

This is the subtlest trap and the one I’d urge you to watch for most carefully. There’s a category of advisor who ran a genuinely strong school years ago, got tired of the grind, sold or closed it, and now teaches an idealized version of what running a school “should” look like — not what they actually did to build it while they were in the arena. It’s easy to romanticize your own history once you’re no longer living inside its daily pressure. The problem is twofold: first, that idealized version was never actually tested in the field the way it’s now being presented; second, and more importantly, it’s simply not what produced their real results at the time. If someone can’t tell you specifically what they did — the actual marketing, the actual pricing, the actual retention systems, backed by what their numbers really were — while they were building the thing, run from that advice. Advice built on nostalgia isn’t strategy.

Top-tier benchmarking: model the top 1–10%, not the middle

A huge share of the advice circulating in this industry comes, well-meaningly, from the middle of the pack — owners who are doing fine, better than most of their immediate circle, and have concluded that qualifies them to teach. But if your goal is a genuinely high-performing, highly profitable school, modeling the middle of the pack will get you to the middle of the pack, at best. You want to study the top 1% and the top 10% specifically — the owners doing half a million to a million-plus a year, or the people who coached them there — because that’s the only group whose systems have actually been proven at the level you’re aiming for. For the fuller picture of what separates a $1M-gross school from one that’s also genuinely profitable, the Million-Dollar growth hub breaks down exactly what those top-tier operations do differently.

Adaptation habit: are they still looking over the horizon?

The final filter is simple: does this person, or this organization, actively look for what’s changing, or are they defending a method because it’s the one they already know? Check their circle of influence. Do genuinely credible people in the industry respect them and reference them? Do they have real feelers out for what’s shifting — in marketing channels, in how families evaluate a school, in what today’s students and parents actually want — or are they teaching a fixed playbook regardless of whether the world around it has moved? An advisor who’s still teaching yesterday’s channel as though it’s cutting-edge isn’t malicious. They’re just ripe and rotting, and if you follow them, you’ll rot right alongside them.

What “maximizing results” actually means

I want to correct a misconception before it does damage: maximizing your results is not just about the top-line revenue number. It’s about four things together — generating strong revenue, keeping students enrolled as long as possible, developing the best possible student and eventually the best possible black belt, and being a genuine pillar of your community, respected by the people and organizations around you, for the long haul. A school that hits an impressive number for eighteen months and then flames out publicly — and this industry has seen some genuinely bad, public flameouts — hasn’t actually maximized anything. The goal is a school that’s stronger ten, fifteen, twenty years from now than it is today, not a spike followed by a collapse.

That long horizon is exactly why retention deserves as much attention as growth. Well-run schools target monthly attrition below 2%, against an industry average of 3–5%, because keeping a student engaged for years instead of months compounds every other investment you’ve made in that relationship — and a new student costs 5–7x more to acquire than to retain, typically $150–$300 in ad spend and staff time per enrollment. Growth without retention is just running in place at a higher volume. If you want the deeper retention mechanics that support a genuinely durable school, the School Growth hub covers the systems side of building something that compounds instead of spiking and fading.

How to actually apply the filter this week

Go through the sources of advice currently shaping your decisions — coaches, consultants, industry personalities, even well-meaning peers — and run each one through the five questions. Did they actually build something real themselves? Are they teaching what’s working now or what worked a decade ago? Can they tell you specifically what they did, not an idealized version of it? Are they benchmarked against the top 1–10%, or the middle? Are they still actively adapting? Any source that fails two or more of those questions shouldn’t be shaping decisions about your pricing, your marketing, or your growth plan.

This isn’t about being cynical toward well-meaning people. It’s about recognizing that sincerity, charisma, and even genuine past success don’t automatically qualify someone to guide you toward a million-dollar operation today. The owners who actually get there are the ones who got deliberate about whose word they took — early, and often.

One more practical habit worth building alongside the filter: schedule a standing quarterly review of your own numbers against this same checklist. Are you green and growing, or have you quietly settled into a plateau that feels comfortable? Pull your net margin, not just your gross. Pull your monthly attrition rate. Pull your cost per enrollment. Compare each one against where it stood a year ago. Owners rarely notice they’ve drifted into “ripe and rotting” in real time — it’s almost always visible only in hindsight, once a competitor with a more current approach has quietly pulled ahead in the same market. A quarterly gut-check, run honestly and without excuses, catches the drift early, while it’s still cheap and straightforward to fix rather than an emergency turnaround years later.

Frequently Asked Questions

How do I tell if a business advisor’s methods are outdated?

Ask them what’s changed in their approach in the last year or two, and ask for specifics, not generalities. An advisor who’s still recommending the exact same tactics they used a decade ago, without having adapted to how families search for and evaluate schools today, is teaching history. Also check whether other credible people in the industry currently reference and respect them — stagnant advisors tend to lose that circle over time.

Is it bad advice if it comes from someone who used to run a successful school?

Not automatically — but be careful of the gap between what they actually did and what they now say they wish they’d done. Ask for specifics: exact pricing, exact marketing, exact retention numbers, from when they were actually running the school. If they can’t produce that level of detail, you may be getting a romanticized memory rather than a proven system.

What does it actually take to build a school worth $500K to $1M+ a year?

It requires modeling the systems of the top 1–10% of the industry rather than the middle of the pack: premium tuition (typically $347–$397/month), a structured 12-month Trial Enrollment, monthly attrition held below 2%, and a marketing engine that keeps adapting to whatever channel is currently working rather than defending whatever worked years ago.
