A groundbreaking manifesto on how belief-when understood, cultivated, and wielded-can change your life, your leadership, and the world.

The one force more powerful than intelligence, money, or charisma?

Belief.

It drives revolutions, elects presidents, topples empires, fuels innovation, and quietly determines your every decision. From the rise of movements to the transformation of a single soul, belief is the unseen engine behind human behavior, leadership, and destiny.

In The Power of Belief, psychiatrist Mardoche Sidor, M.D., social worker Karen Dubin, Ph.D., LCSW, and the SWEET Institute take you on a powerful journey through the psychology, strategy, and soul of belief. Drawing from clinical insight, historical case studies, and cutting-edge science, this book unpacks how belief systems are formed, weaponized, healed, and transformed.

Inside you'll discover:

• Why belief-not talent or intelligence-separates great leaders from forgotten names
• What Donald Trump's rise teaches us about conviction, charisma, and collective psychology
• How to dismantle limiting beliefs and build a system that aligns with your highest purpose
• What history's most impactful leaders believed-and how their beliefs reshaped the world
• How to inspire others, lead movements, and create lasting legacy through belief-driven influence

Whether you're a changemaker, clinician, educator, executive, or someone searching for more meaning, this book will challenge you, empower you, and invite you to believe again-on purpose.

Because when you master belief, you don't just change your life.

You change the future.

Praise for The Power of Belief

• This compelling book offers a timely and thought-provoking exploration of how belief-not just intelligence or expertise-shapes leadership, movements, and personal transformation. While I do not share the political views or values of certain figures discussed, I deeply appreciate the authors' ability to examine belief as a psychological and social force that transcends ideology. A powerful and important read for anyone interested in how ideas drive action and change.
