Ten years ago, perhaps the single most widely used “generic” organization-building system was the tape album, “How to Earn at Least $100,000 a Year in Network Marketing.” That album is no longer available because author Randy Gage has replaced it with his up-to-date, souped-up and soup-to-nuts system, Duplication Nation.

The kit is available in three formats (in ascending order of price): as a set of 12 audio CDs, 12 DVDs, or a “Leadership Kit” that includes the CDs and DVDs plus a handful of extras. The CD version is great for training yourself; the DVDs are ideal for training others; the extras in the full kit (including nine copies of a well put together “Study Guide”) are worth it for the assist they offer in training and…well, duplication.

Chapter 1 of the Study Guide opens with these words: “The real magic of this business is the duplication.” On the next page, Gage amplifies: “You can’t sponsor your way to the top of your comp plan, and you can’t retail your way there. You can only duplicate your way there. The key question to ask is not, ‘Does it work?’ but, ‘Does it duplicate?’”

That’s the focus of the whole system: to give you the essential skills to allow you to find and qualify prospects, make compelling presentations and sponsor them—all in a way that duplicates.

Over the decade since “How to Earn $100,000…” hit the market, the profession has grown and changed. So has Gage, and so has his training.

The most obvious difference is that between 1995 and 2005, the Internet happened, and Duplication Nation has absorbed it seamlessly. But the more fundamental difference is in Gage’s overall approach, which has softened and broadened. In the earlier system, as Gage points out himself, “I was advocating a clearly defined system. Given the changes in the business … and the advent of much new technology, I have changed that here. Instead of trying to micro-manage your group, I concentrate on teaching you the necessary skill sets and paint the big picture you need to be aware of.”

That he does, and nobody does it better. The two skills for which Gage is perhaps best known are his marketing (his direct mail campaigns are masterpieces) and his live presentation. A greater skill, though, is one that is more central to the topic: Gage has a masterful grasp of human nature.

For example, his teaching on the principle of “edification”—which is generally overpushed but underapplied in our business—takes the idea to places most don’t go. It’s not just a question of “edifying” your upline (the word, unlike its Biblical and traditional counterpart, is used in network marketing to mean “to talk up or build the reputation of”), Gage shows how and why it’s critical to edify your downline, your cross line, your company, and the profession itself. Why? Because it fosters duplication.

Priceless insights—at any price.
