What if the biggest thing holding you back isn’t your skills, your resources, or even your discipline—but your beliefs?

In this conversation, Jay sits down with Nir Eyal to unpack the hidden force behind motivation and persistence. While most people think success comes from knowing what to do, Nir makes a compelling case that the real driver is belief. If you don’t believe the effort will pay off—or that you’re capable of sustaining it—you’ll quit long before results show up.

They break down the “motivation triangle” of behavior, benefit, and belief, and explore how limiting beliefs quietly shape your decisions, your relationships, and your ability to follow through. You’ll also learn a practical method to uncover those beliefs and replace them with ones that actually serve you.

This episode also tackles a critical question: when should you keep going, and when should you quit? Nir shares a simple three-part framework to help you decide with clarity instead of emotion.

If you’ve ever felt stuck, inconsistent, or ready to give up, this conversation will change how you see yourself—and what’s possible.

Challenge of the Week:

Identify one limiting belief that’s holding you back. Write it down, then ask yourself: “Could the exact opposite be true?” Create a new belief that serves you—and repeat it when things get hard.
