"A Flexible Mind: Tools for Integrating Psychological Flexibility and the Enneagram into Your Personal Growth" by E. Marcelo Aguirre integrates the teachings of the Enneagram of Personality with tools from Acceptance and Commitment Therapy (ACT). The book proposes that psychological flexibility—comprised of six core skills (present-moment awareness, cognitive defusion, acceptance, self-as-context, values clarification, and committed action)—is essential for mental well-being. It explores how each of the nine Enneagram personality styles can apply these skills to overcome ego rigidity and live more authentically, in alignment with personal values. Ultimately, the text argues that personal growth is an ongoing journey of self-discovery and intentional action, where perseverance is key to transforming automatic patterns and building a purposeful life.
