He runs a martial arts school in <strong>Mankato, Minnesota<\/strong>, and he&#8217;d followed Stephen Oliver from a distance for over a decade while assuming Oliver was &#8220;just a money guy&#8221; who didn&#8217;t care about the martial arts. That assumption, he estimates, cost him a quarter-million dollars in the short run and millions over the long run. When he finally joined Martial Arts Wealth Mastery, his school <strong>doubled from about $28,000 a month to $56,000\u2013$57,000 a month<\/strong> \u2014 and posted a record December with over $90,000 in cash and more than $200,000 in receivables in a single month.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Watch Colby Winkler&#8217;s story<\/h2>\n\n\n\n<div style=\"max-width:820px;margin:20px auto;\"><div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;border-radius:12px;box-shadow:0 8px 30px rgba(0,0,0,.35);\"><iframe style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;\" src=\"https:\/\/www.youtube.com\/embed\/tJE6QagA3kE?rel=0\" title=\"Colby Winkler, Mankato MN, on Martial Arts Wealth Mastery\" loading=\"lazy\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">From $28,000 to $57,000 a month<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Colby had been in business a long time and was hunting for the next level. He&#8217;d tried several consulting groups and &#8220;all kinds of things&#8221; to take his school, his students, and his curriculum a step further. What he&#8217;d never found, until Martial Arts Wealth Mastery, was help that wasn&#8217;t just generalized information \u2014 people who actually knew, step by step, how to take a school to the next level.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The results followed. When he started, his school was grossing about <strong>$28,000 a month<\/strong>. It now runs around <strong>$56,000 to $57,000 a month<\/strong> \u2014 roughly double. In his words, the benefit he&#8217;s gotten has been &#8220;enormous&#8230; hands-down, top-notch, second to none,&#8221; touching his business, his personal life, and his students&#8217; lives alike.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The record December: $90K cash, $200K in receivables<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Beyond the steady doubling of his monthly gross, Colby had some genuinely eye-opening record months. The standout was a December in which his school did <strong>over $90,000 in cash and more than $200,000 in receivables in that single month<\/strong>. He&#8217;s clear about what made it possible: &#8220;That was something we had never done before&#8230; we wouldn&#8217;t have done that without the help of Martial Arts Wealth Mastery.&#8221; That kind of month is exactly what the renewal, upgrade, and enrollment systems are built to produce \u2014 not by accident, but on purpose.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">&#8220;I didn&#8217;t want to be a sellout&#8221;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Colby&#8217;s biggest hesitation before joining is one a lot of serious martial artists share. Having been part of a few groups and talked to plenty of self-described consultants, he was worried about becoming a &#8220;sellout&#8221; \u2014 about being bought, and about pushing his curriculum and his students out of the forefront in the name of money. He believed deeply that if you take care of the martial arts, the money can follow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What he found inside the group was the opposite of what he feared. &#8220;It&#8217;s actually totally the opposite,&#8221; he says. The focus is on how to teach better martial arts, how to run a better grading, how to implement things in a better way \u2014 and <em>then<\/em>, as the school owner, the money follows. The money isn&#8217;t the number-one focus. You take care of the other things, and the revenue tends to take care of itself. For an owner who was afraid quality would be sacrificed, that was the reassurance that mattered most.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The $250,000 first impression<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here&#8217;s the most honest and most valuable part of Colby&#8217;s story. He&#8217;d been aware of Stephen Oliver for 10 to 15 years \u2014 and for most of that time he&#8217;d written him off. His first impression was that Oliver was &#8220;just a money guy,&#8221; all about the business and not about the martial arts. He wasn&#8217;t impressed, and that judgment kept him on the sidelines for years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When he finally decided to just try it, he realized how wrong that first impression had been \u2014 and how much it had cost him. &#8220;I cost myself a quarter-million dollars by waiting around and not trying this thing out,&#8221; he says, and figures he &#8220;probably missed millions of dollars in income and revenue&#8221; by not implementing the strategies sooner. His advice to other owners is pointed: don&#8217;t let a first reaction or a first meeting keep you from something that could improve your school, your life, and your students&#8217; lives.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Colby&#8217;s story should teach you<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Waiting has a price tag.<\/strong> Colby put a number on it: a quarter-million dollars in the short run, and by his estimate millions over the years he stayed on the sidelines.<\/li><li><strong>Quality first is not the opposite of profit.<\/strong> The fear of &#8220;selling out&#8221; is backwards \u2014 better martial arts, better grading, and better systems are exactly what make the money follow.<\/li><li><strong>Record months are built, not lucky.<\/strong> A $90,000-cash, $200,000-receivables December comes from renewal, upgrade, and enrollment systems run on purpose.<\/li><li><strong>Don&#8217;t let a first impression cost you.<\/strong> Colby misjudged the coaching for over a decade.
