"Millions feel adrift and purposeless, despite having outwardly successful lives. John R. Miles shows why this happens--but more importantly, how to fix it in your own life. Read The Mattering Effect and take ownership of your life." --Arthur C. Brooks, #1 New York Times bestselling author of The Meaning of Your Life

"Read this book if, as Miles writes, you want to 'stop trying to prove you belong and begin receiving the quiet evidence that you already do.'"-Dana Suskind, MD, Professor of Surgery at the University of Chicago, and New York Times bestselling author of Human Raised

A call to address the urgent crisis of our time--the loss of significance in our lives--by restoring mattering as the missing link between personal well-being and collective repair.

"The most important person who needs to know you matter is you." -- Gordon Flett, professor emeritus of psychology at York University

If you've ever wondered, If I stopped performing, producing, fixing, achieving, proving, would I still matter? then this book is for you. As John R. Miles explores The Great Erasure happening in our lives--the sense of loneliness and disengagement despite outward success--he also provides a way for you to remember that you mattered before any professional or personal titles or achievements.

Drawing on research in psychology, neuroscience, social science, and contemplative traditions, as well as deeply personal stories, Miles examines the cultural shift that has replaced human significance with human usefulness, resulting in exhaustion, self-erasure, and quiet despair. Where others have also diagnosed the symptoms, Miles identifies a deeper cause and offers a solution through M.A.T.T.E.R., a research-based framework grounded in six elements―meaning, autonomy, trust, time, energy, and reciprocity―that, when used together, can restore sustainable significance, dignity, and spiritual coherence. Inspired by hundreds of conversations with today's researchers and thought leaders, the framework helps you gain clarity on why success doesn't erase emptiness; offers practical tools to restore significance in your work and relationships, and shows what it takes to build a life of meaning, reciprocity, and genuine mattering.
