The Hemingway Principle

We're told more is always better—more options, more resources, more freedom. But David Epstein spent years looking at the science, and what he found challenges that assumption. Constraints don't just force creativity. According to the research, they often generate it.

In this episode, Mina Seetharaman talks with David Epstein, author of Inside the Box: How Constraints Make Us Better and the New York Times bestseller Range, about why total freedom tends to produce mediocre work, how the best leaders design limits on purpose, and what the history of companies like General Magic and Pixar reveals about the relationship between boundaries and breakthrough. 

David was previously on the Creative Confidence Podcast to discuss Range: Why Generalists Triumph in a Specialized World. This conversation picks up where that one left off.
