Steven Hayes's book, A Liberated Mind, which introduces Acceptance and Commitment Therapy (ACT) as a method for improving well-being. The book argues that trying to suppress difficult thoughts and emotions is often counterproductive, leading to psychological inflexibility and suffering. Instead, Hayes proposes six core ACT processes, or "pivots," including defusion from thoughts, acceptance of feelings, presence in the moment, self-as-context, values clarification, and committed action. Through personal anecdotes, research findings, and practical exercises, the book illustrates how applying these principles can foster psychological flexibility, enabling individuals to live more meaningful and fulfilling lives despite challenges like anxiety, depression, chronic pain, and relationship issues. Furthermore, the text explores applications of ACT in various contexts, such as health behaviors, relationships, work performance, and even social transformation, highlighting its potential for broader societal impact.
