Dr. Sue Varma

“In Big Trust , Shadé Zahrai offers the perfect inner complement to Building a Second Brain ... Zahrai shows that productivity without self-trust leads only to burnout and doubt—that knowledge alone isn’t enough without the confidence to act on it. Her framework of Acceptance, Agency, Autonomy, and Adaptability gives readers the missing operating system for their inner world: a way to move through self-doubt with clarity, courage, and composure. This book is essential reading for anyone who’s built external systems of knowledge and is now ready to cultivate the internal trust to use them fully.”

“Shadé Zahrai has written a book that feels like someone finally pulled back the curtain on self-doubt. She doesn’t just tell you to ‘believe in yourself’; she shows you how—with proven tools, mindset shifts, and habits that build something far more powerful: self-trust. It’s part science, part story, and part wake-up call. If you’ve ever silenced yourself in a meeting, second-guessed your abilities, or waited to feel ‘ready,’ Big Trust will feel like someone finally turned the lights on. It’s practical, powerful, memorable, and deeply human. And what I love most? It’s like a magician revealing all their secrets.”
