Marisa Peer Announces Powerful New Book Revealing How Childhood Beliefs Shape Adult Life – And How to Rewrite Them
World-renowned therapist, bestselling author, and creator of Rapid Transformational Therapy (RTT), Marisa Peer, has announced that her highly anticipated new book, Your Mind, Your Rules, will be published on 9 April 2026, with pre-orders opening on 13 February.
Drawing on more than 40 years of clinical experience working with CEOs, entrepreneurs, elite athletes, celebrities, royalty, and individuals worldwide, Your Mind, Your Rules explores the subconscious beliefs or “rules” formed in childhood that quietly govern adult behaviour, relationships, self-worth, success, and emotional wellbeing.
In the book, published by Stephen Bartlett’s publishing arm, Flight Books, Marisa reveals why willpower alone rarely creates lasting change, and how identifying and rewriting these internal rules can transform every area of life.
“So many people are living their lives by rules they never consciously chose, but were formed through childhood experiences, words spoken to them or moments where they decided who they had to be in order to feel connected, loved or safe,” says Marisa.
“These rules then quietly shape how we think and feel about ourselves, how we show up in our careers and relationships, and what we believe is possible for us.
“The moment you learn to rewrite those rules, everything changes. You stop repeating the past, sabotaging yourself, and you begin to think, feel, act and succeed from a place of confidence, self-worth and choice – not conditioning.”
Rather than a trend-led self-help title, Your Mind, Your Rules is a definitive work, combining elements of neuroscience, psychology, and decades of therapeutic insight with practical tools readers can apply immediately.
The release comes at a time when, according to the World Health Organization, one in eight people worldwide lives with a mental health disorder, with depression and anxiety costing the global economy over £1 trillion annually in lost productivity.
Your Mind, Your Rules is part of Marisa’s broader mission to elevate conversations about mental health, relationships, parenting, and emotional resilience, and to provide accessible, effective tools for lasting change.
The book builds on her vast body of work, including her global RTT training programme, the I Am Enough movement, and her commitment to transforming mental health worldwide through her programs, books, and social media channels.
