If you think building a custom GPT is just clicking a few buttons and uploading whatever docs are lying around… this episode is your wake-up call.

Christopher’s back—and this time, he’s breaking down the real prep work that needs to happen before you even think about launching your own AI assistant. Because here's the truth: AI isn’t magic. If your data’s a mess, your output will be worse. (And if you're still skimming AI responses instead of reviewing them? You're asking for a marketing disaster.)

In this episode, you’ll learn what actually goes into building an effective AI tool—from knowing your objectives to structuring data properly to avoiding the skimming trap that kills results. Whether you're a marketer trying to speed up content, a business leader exploring GPTs, or just someone who’s tired of generic, inaccurate AI output, this is your no-BS guide to doing it right.

Christopher also drops some spicy observations about the sudden influx of “AI experts” (hint: they were in real estate last year), and calls out the hype from the snake oil sales crowd.

 

What’s Inside:

  • Why most custom GPTs suck—and how to make sure yours doesn’t
  • The most prominent mistake marketers make when uploading data (and how to fix it)
  • How to avoid the skim-and-send syndrome that's sabotaging your results
  • A behind-the-scenes look at Christopher’s process for prompt refinement
  • The unsexy but essential truth about planning, testing, and revising AI tools

From the Episode:

“Fast isn’t the goal. Accurate is. If you don’t take the time to get your data right, your AI output is just dressed-up garbage.”

If you’re serious about using AI to elevate—not dilute—your marketing, this episode will give you the real talk and tactical steps to get started the right way.

Medal of Honor: Stories of Courage

Medal of Honor: Stories of Courage

Rewarded for bravery that goes above and beyond the call of duty, the Medal of Honor is the United States’ top military decoration. The stories we tell are about the heroes who have distinguished themselves by acts of heroism and courage that have saved lives. From Judith Resnik, the second woman in space, to Daniel Daly, one of only 19 people to have received the Medal of Honor twice, these are stories about those who have done the improbable and unexpected, who have sacrificed something in the name of something much bigger than themselves. Every Wednesday on Medal of Honor, uncover what their experiences tell us about the nature of sacrifice, why people put their lives in danger for others, and what happens after you’ve become a hero. Special thanks to series creator Dan McGinn, to the Congressional Medal of Honor Society and Adam Plumpton. Medal of Honor begins on May 28.
