Many folks now echo the guidance that the Great Demo! team has been teaching for years BUT: They don’t know the details!
They trumpet this approach, but they don’t understand what to present, how to present it, when to do it (strangely enough!), and even why this method is so effective.
Their results suffer and are far from what is possible or desired.
For the full story and to enjoy a much richer set of rewards, read Great Demo! or, even better, take a Great Demo! Workshop. Get your guidance from a master, not a novice!
