Knowing Thyself
Ancient Wisdom for Tomorrow’s Leaders
Carved into the Temple of Apollo, the words “Know Thyself” still echo as the essence of authentic leadership. My new book, KNOWING THYSELF, distills that 2,500-year legacy into a forward-looking guide for navigating an age of disruption and change.
Across 21 pathways, each chapter weaves a timeless idea from early Greek thinkers—like Heraclitus and Socrates—with reflective questions for today’s challenges, enriched by inspirations drawn from the wild landscapes of Greece.
The result is a fresh and original approach to leadership—one that invites you to align values with purpose, foster meaningful dialogue, and transform uncertainty into clarity.
By the final page, you’ll be equipped to:
• Lead with greater self-awareness, purpose, and adaptability
• Build trust and collaboration through genuine conversation
• Find daily inspiration in nature and practical philosophy
In an increasingly fragmented world, KNOWING THYSELF offers a transformative route to connection—and to the leader you are ready to become.
