In "The Promises of Giants," former NBA player turned psychologist John Amaechi redefines leadership for everyone. Called "one of the most powerful books ever written about leadership" by Adam Grant, this bestseller brought readers to tears while winning the 2021 Porchlight Business Book Award.
John Amaechi, New York Times and Sunday Times bestselling author of The Promises of Giants, is an organizational psychologist, leadership expert, and former NBA pioneer. As the first Briton to play in the NBA, his eight-year career with teams like the Cleveland Cavaliers and Orlando Magic informs his work on high-performance team dynamics and ethical leadership.
Amaechi holds a PhD in psychology, founded the consultancy APS Intelligence, and serves as Professor of Leadership at the University of Exeter Business School. His insights into organizational behavior stem from both his athletic career and advisory roles for FTSE 100 companies.
Amaechi's memoir Man in the Middle—a groundbreaking revelation as the first openly gay NBA player—complements The Promises of Giants, which blends psychological frameworks with real-world leadership challenges. Recognized with an Order of the British Empire (OBE) for services to sport and equality, he frequently advises global institutions and speaks at elite forums. The book has been endorsed by industry leaders for its actionable strategies to build inclusive, purpose-driven organizations.
The Promises of Giants explores leadership strategies for achieving personal growth and organizational success through 14 actionable commitments. John Amaechi, a psychologist and former NBA player, challenges readers to embrace self-awareness, accountability, and cultural responsibility. The book blends behavioral science with real-world examples, emphasizing how individuals in influential roles (“giants”) can drive systemic change while avoiding unintended harm.
This book is ideal for professionals, executives, and aspiring leaders seeking transformative frameworks for inclusive leadership. It resonates with those interested in psychology, workplace culture, and social equity. Amaechi’s insights are particularly valuable for individuals navigating career transitions or managing teams in high-stakes environments.
Yes—readers praise its thought-provoking analysis of leadership and actionable advice. Blinkist users describe it as “highly addictive” for its concise insights, while critics highlight its relevance to modern challenges like diversity and emotional intelligence. The book’s blend of academic rigor and practical strategies makes it a standout in leadership literature.
Amaechi introduces concepts like:
These frameworks emphasize intentional leadership over accidental influence.
Amaechi draws parallels between athletic pressure and corporate leadership, using his time with the Orlando Magic and Utah Jazz to illustrate resilience and authenticity. His experiences as the first openly gay NBA player inform discussions on overcoming adversity and fostering psychological safety in teams.
The “giant” represents anyone in a position of influence, from managers to community leaders. Amaechi argues that giants must recognize their power to inadvertently harm others through indifference or inaction, urging proactive accountability.
It provides tools for dismantling toxic norms, such as prioritizing timely feedback and modeling vulnerability. Amaechi stresses that leaders must “be present” beyond transactional needs, fostering trust through consistent engagement.
Some reviewers note the book’s abstract concepts may overwhelm readers seeking step-by-step guides. Others suggest it leans heavily on Amaechi’s personal journey, which, while compelling, risks overshadowing broader applications.
Unlike transactional guides like Atomic Habits, Amaechi’s work focuses on ethical stewardship and systemic change. It complements Brené Brown’s vulnerability research but adds a unique lens on power dynamics and marginalized identities.
The book encourages defining success beyond metrics, such as mentoring others and challenging inequitable systems. Amaechi’s “giant” philosophy aligns with LinkedIn’s 2025 trends on purpose-driven leadership and emotional agility.
While standalone, the book expands on themes from his memoir Man in the Middle, particularly his journey as a gay athlete and psychologist. It also incorporates principles from his TEDx talk You Can’t Be Part Time.
As workplaces grapple with AI integration and generational shifts, Amaechi’s emphasis on human-centric leadership offers a counterbalance to productivity-driven cultures. His strategies help organizations retain talent during the “Great Reshuffle” era.

Picture a crowded New Year's Eve dance floor. Bodies swaying, music pounding, champagne flowing. You're lost in the moment, arms flailing with abandon-until your elbow connects hard with someone's face. Blood. A broken nose. Your profuse apologies meet only a cold, vacant stare. Your remorse changes nothing. The damage is done. This isn't a cautionary tale about dancing-it's about power. When you occupy space in the world, especially when you hold any form of influence, you can't simply opt out of responsibility because you were "just having fun" or "didn't mean it." Leadership isn't a costume you wear to important meetings and remove when it's inconvenient. You're always a giant to someone, whether you acknowledge it or not. Your casual glance can make or ruin someone's day. Your throwaway comment can echo in someone's mind for years. There are no breaks from this reality, no magic potion that shrinks you back to normal size when you'd rather blend in. The question isn't whether you have power-it's what you'll do with it.
