In this episode I break down the difference between slide decks and slide docs—and talk about designing intentionally for each.

Many presentation problems don't stem from weak ideas or poor analysis. They come from using the wrong artifact for the job. Slides overloaded with text are often treated as presentations when they're really documents meant to be read. The result? Confused audiences, long meetings, and diluted messages.

I explain why slide decks and slide docs serve fundamentally different purposes—and why trying to make one file do both almost always fails.

In this episode, you'll learn:

• Why slide decks are spoken artifacts designed to support your voice, not replace it

• How slide docs function as read artifacts that must stand on their own without explanation

• A simple rule of thumb to help you choose the right format before you start building

Whether you're preparing for class presentations, team meetings, interviews, or client-facing work, understanding this distinction will immediately improve your clarity and credibility.

Data doesn't persuade. Insight does.

In this episode, I break down what effective data visualization really means—and why most charts fail to do their job. This isn't about making slides look prettier. It's about helping your audience think clearly, decide faster, and trust your analysis.

Drawing on lessons from Edward Tufte's work and Good Charts by Scott Berinato, Gregory explains how to move from cluttered, confusing visuals to charts that make the point unmistakable.

You'll learn:

• Why every chart should answer one clear question—and how to define it before you design

• How to match chart types to intent, so your audience doesn't have to work to understand your message

• What it really means to simplify ruthlessly, including what to remove, mute, or highlight

• Why message-driven titles dramatically improve comprehension

• How context, annotation, and design for the room turn data into evidence

Whether you're preparing for class presentations, internship updates, or executive decks, this episode will help you stop using charts as decoration—and start using them as tools for influence.

The Glance Test is a simple but powerful rule for slide design: if your audience can't understand the point of a slide within a few seconds, the slide isn't doing its job.

In this episode, I explain why slides that demand too much reading or decoding cause audiences to stop listening—and how the Glance Test helps protect attention during live presentations. You'll learn how strong, message-driven titles anchor understanding, why visual simplicity matters more than precision, and how to design slides that support your voice rather than compete with it.

The episode also explores the difference between slides meant to be spoken versus read, where detail really belongs, and how passing the Glance Test leads to calmer delivery, clearer pacing, and more persuasive presentations. If your slides feel busy or your audience seems distracted, this episode offers a practical framework to fix both.
