Why You Know What to Do, But Still Don’t Do It

Lasting change begins with a shift in both mindset and behavior.
Many people remain stuck in self-defeating patterns because of
unconscious narratives, emotional triggers, and a disconnection
from their body’s inner wisdom. Change isn’t just about willpower
or information—it’s about learning to rewire the brain through
small, intentional actions that generate powerful emotional
feedback loops. Identity transformation happens not through
repetition, but through experiences that create a sense of success.
In a world flooded with conflicting advice and manipulative
marketing, reclaiming agency requires tuning into your own signals,
building self-trust, and recognizing that behavior change is a
design challenge—not a character flaw. Empowerment comes from
realizing that the ability to change is built into who we are as
humans. In this episode, I speak with Tom Bilyeu, Dr. Rangan
Chatterjee, and Dr. BJ Fogg about cracking the nut of behavior
change. Tom Bilyeu is a filmmaker and serial entrepreneur best
known as the co-founder of Quest Nutrition, a billion-dollar
company built to combat metabolic disease through value-driven
innovation. After nearly a decade of chasing financial success and
feeling unfulfilled, he realized the importance of loving the
struggle itself. This insight led him and his partners to shift
focus from profit to purpose. Quest quickly became the second
fastest-growing company in North America, according to Inc.
Magazine. After achieving significant personal wealth, Tom turned
to the other global crisis he saw—disempowering mindsets. To
address this, he co-founded Impact Theory, a media studio with his
wife, Lisa Bilyeu. Their mission is to scale mindset transformation
by producing empowering content that shifts the cultural
subconscious. Just as Disney built the most magical place on Earth,
the Bilyeus aim to build the most empowering one. Dr. Rangan
Chatterjee is regarded as one of the most influential doctors in
the UK. A practicing GP for the last two decades, Dr. Chatterjee
wants to inspire people to transform their health by making small,
sustainable changes to their lifestyles. Host of the #1 Apple
podcast, Feel Better, Live More, and presenter of BBC 1’s Doctor in
the House, Dr. Chatterjee is the author of 5 Sunday Times
bestselling books and his TED Talk, “How to Make Diseases
Disappear,” has now been viewed over 4.8 million times. His newest
book is Happy Mind, Happy Life: The New Science of Mental
Well-Being. Dr. BJ Fogg is a behavior scientist, author, and
founder of the Behavior Design Lab at Stanford University, where he
has researched human behavior since 1998. He developed the
groundbreaking “Behavior Design” system, which explains how
behavior works and how to design it effectively. Over the past
decade, his lab has focused on practical applications—from helping
people navigate coronavirus-related challenges to training climate
change professionals in behavior change strategies. BJ is also the
creator of the “Tiny Habits” method, a simple, science-backed
approach to habit formation that has helped over 40,000 people make
lasting life changes. His work empowers individuals and
organizations to design behavior that benefits both people and the
planet. He shares his insights in the New York Times best-selling
book, Tiny Habits: The Small Changes That Change Everything. This
