Growth Mindset Psychology: The Science of Self-Improvement
Sam Webster Harris | Growth Mindset Psychology
Most self-help advice is guesswork dressed up as wisdom. We dig into psychology, neuroscience, and behavioral science to find what actually changes lives.
WHY LISTEN?
Over 8 million downloads because we answer the questions that matter: How do I build mental strength? What creates lasting motivation? How can I understand my own mind well enough to work with it, not against it?
This podcast is for curious skeptics who want frameworks backed by psychology studies, not Instagram quotes. Whether you're navigating procrastination, building self-discipline, or designing your own philosophy for a life well lived—we explore the hidden psychology behind real change.
WHAT YOU'LL GET
Mental models and simple techniques from cognitive psychology, positive psychology, and ancient wisdom traditions like Stoicism and Buddhism.
Being a human can be confusing, learning about it doesn’t have to be.
We cover everything from emotional intelligence and habit formation to brain health and the nervous system.
WHAT YOU DON’T GET
No pseudoscience. No oversimplified "hacks." No hustle porn.
Just practical insights on mindset improvement, self-development, and human psychology that respect your intelligence and mental health.
THE APPROACH
Instead of telling you what to think, we explore how thinking works. Armed with psychology studies, social science research, and relentless curiosity, we uncover the mechanics of belief change, attitude change, and personal development.
Success is personal. You might want to leverage your neurodiverse strengths, build a business, or simply discover how to be happier. We provide the mental frameworks to pursue your definition of success with mental strength and self-care that fits your life.
YOUR HOST
I'm Sam Webster Harris—a lifelong learner with ADHD and an obsession with finding answers to hard questions. After launching businesses, traveling the world, and nearly dying a few times, I concluded that psychology and science are where real wisdom lives.
This show is my excuse to dive deep into health and fitness research, behavioral psychology, and cool science while helping you build genuine self-discipline and motivation.

Your Nervous System Has Been Running Your Life - How to finally take control with Stephen Porges (Inventor of Polyvagal Theory)
How the science of the vagus nerve explains anxiety, ambition, burnout, and the art of becoming who you actually are.
Humans, might be the most sophisticated organism on Earth (capable of writing symphonies, landing on the moon, and inventing artisanal sourdough). Yet at our core, we are running threat-detection software that predates the dinosaurs.
Stephen Porges, the scientist who mapped the vagus nerve's extraordinary influence on human behaviour, joins us to explain why this ancient wiring is quietly making most of your big life decisions for you. The good news is that evolution, for once, gave us a rather elegant solution. Safety — genuine, physiological safety — unlocks curiosity, creativity, and the particular satisfaction of becoming who you actually are. The even better news is it's achievable without a retreat, a cold plunge, or a subscription.
What you'll take away:
Why your gut reactions are data, not drama
How the environments we build either cage or liberate our best thinking
Why the most calming people aren't trying to be calm
Your nervous system has been waiting for this conversation.

The Psychology of Risk: How Near Death Experiences Help you Quit a Good Life to Pursue a Great One - w. Talia Lazarus
We are all waiting for permission that is never going to come. We cling to the illusion of a safe life, pretending that incremental improvements are the same thing as actual growth.
Talia Lazarus didn’t plan on changing her life; the universe intervened in the form of a devastating bus accident. In the agonizing space of her recovery, she confronted a profound truth: she was living a script written by someone else. So, she burned it down. This episode is about the radical shift from accepting what is, to choosing what could be. It explores the "doorstep mile"—the immense, invisible friction of taking the first step toward true purpose. You don't need a catastrophe to change your posture in the world. You just need to stop looking in the rear-view mirror and realize that your constraints are entirely invented.
How to identify the difference between real growth and the illusion of progress.
The art of embracing the "doorstep mile" to finally ship your true work.
Why surrendering your past is the only way to build a meaningful future.
Listen to this conversation and discover how to stop waiting, step over the threshold, and choose a great life today.
