📚Book Review: The Black Belt in Leadership: 20 Tested Lessons from the Dojo to the Boardroom

In The Black Belt in Leadership, Aslak de Silva bridges the worlds of martial arts and corporate leadership with clarity, humility, and practical wisdom. Drawing on his experience as both a world champion martial artist and a two-time multinational CEO, de Silva distills twenty lessons that are just as relevant on the dojo floor as they are in the boardroom.

This book isn’t another collection of recycled business strategies. Instead, de Silva uses martial arts philosophy—discipline, resilience, respect, and continuous learning—to highlight the mindset shifts leaders need to thrive. His stories are engaging and vivid, showing how timeless principles of training, focus, and humility can shape how we manage teams, make decisions under pressure, and build trust.


🥋What’s Inside

  • Part I: The Dojo of Discipline
  • Part II: The Mindset of a Master
  • Part III: The Inner Fight
  • Part IV: The Path Forward

Each section builds on the idea that leadership is not about control but about character, self-awareness, and the ability to stay centered when everything around you feels unstable.


💡Key Highlights

Lesson 4: Progress Over Perfection – The Coachable Leader’s Advantage

True leadership isn’t about being perfect—it’s about embracing progress. De Silva admits that when he first started in sales, he lacked experience. But as a martial artist, he was coachable, open to feedback, and resilient in the face of correction.

“Martial arts taught me that the moment you think you’re untouchable, someone finds your opening.”

Lesson 5: Leading Through Contradiction in a World That Does Not Make Sense

Leadership means constant change. Success is temporary, and you won’t win every time. What matters most is staying true to your values without hiding behind them as excuses.

“I’ve always done it this way” should never be a reason to stop learning and growing.


Why You Should Read It

The lessons in this book are grounded in lived experience and paired with actionable takeaways. Most chapters end with reflection questions, making it easy to apply insights directly to your life and leadership journey. The conversational tone and straightforward language make it an accessible, inspiring read for anyone—executives, managers, or individuals simply striving to grow.

De Silva reminds us that leadership is less about appearing strong and more about staying centered when the world shakes. Most importantly, the finest leaders are not always the smartest—they’re the ones trained to lead under pressure.

So step into the dojo and pick up your copy of The Black Belt in Leadership. It’s an ultimate guide to leading with power, presence, and principle.

“You do not need a martial arts background to lead like a black belt. But if you want to move with clarity, resilience, and presence—especially under pressure—you need to train like one.”

Rating: 4 out of 5.

Book review: ‘The Girl from Wudang’ by PJ Caldas

‘The Girl from Wudang: A Novel About Artificial Intelligence, Martial Arts and Immortality’ by PJ Caldas. Photo: Amazon

PJ Caldas, a.k.a PJ Pereira, the author of multiple best-selling novels in Brazil, was named one of the most important writers of the 21st century by the Dictionary of Brazilian Literature. He published four books inspired by the mythology carried to the country by the African diaspora and reached the top five best-selling titles multiple times. PJ is also a martial artist with 40 years of experience in combat sports, including kempo, karate, tai chi, and Brazilian jiu jitsu. In 2023 he was named Jury President of the Artificial Intelligence Awards at the Art Director’s Club and curated a Global immersive exhibit of designers collaborating with AI, called ADC101+1, as a way to explore the use of this emerging technology as a creative tool. His new book “The Girl from Wudang” is a story about immortality, martial arts, and AI that will change the way you look at life, science, and the crazy times we are living in.

“The Girl from Wudang” – My Name is Tigress and I am immortal. This is my story. Embark on a mind-bending journey with Tigress as she navigates the confusing jumps of conscience that throw her between tender moments of her childhood practicing Tai Chi in China, the most violent cage fights in California, and a secret lab where scientists experiment with her brain. She was raised in a traditional Chinese setting, immersed in Tai Chi and the Dao, but life soon takes her to California where she gets involved in professional fighting, which she loves. The story begins with an internet Blackout and Tigress is watching it unfold on television in her Oakland home and then decides to go for a jog around the neighborhood. Trouble always seems to find her, or she goes looking for it, but either way, she gets involved in a brutal street fight. Then there is a flash and she is transported to another location. This is Tigress’ life, and she shares her experiences as well as the journey that completely changes her life.

In “The Girl from Wudang,” PJ Caldas gives readers a look into the life of a confident, strong, and self-reliant fighter who evolves from a street fighter to a selfless immortal being. She is a trained fighter, and at first she is smug, but her intent is to teach women to fight: “When it comes to fighting, here’s the difference between a guy and a girl: we know they underestimate us. And I love to make them regret that.” Searching for a way to alleviate her chronic headaches, she allows herself to be part of an experiment and that is where cutting edge technology steps in. Tigress is telling her story, so it is in the first person point of view and the narration, especially the fight scenes, are highly descriptive: “My heels smash his sternum, making a crack and a puffing sound, though momentum and idiocy keep pushing his hips forward.” At first, the footnotes seem out of place, but they become useful when explaining Chinese culture and the author’s thought processes and other background information. The action is fast paced but the sudden jumps in location can seem confusing and some of the fight action is bloody and violent. Regardless, this speculative science fiction novel expertly combines ancient traditions, modern day technology/science, spirituality, and martial arts. It is a must read for fans of cyberpunk and science fiction thrillers by William Gibson and Stieg Larsson.

“This strange dimension where I live, this place nerds call ‘the cloud’ isn’t the Dao of my ancestors. Though, from where I stand, I can hear everything.”

“The Girl from Wudang” – Tigress is immortal. This is her story. Yinyin, called Tigress, was raised in the sacred mountains of Wudang, where her life was about Tai Chi, the Dao, and trying to balance her yang with yin. She had never heard of Artificial Intelligence or neuroscience. But then her overpowering yang sets her on a course to the Bay Area to become a professional fighter.

For as long as she could remember, Yinyin had been told she was poised to become part of something big, but what “big” turned out to be was beyond her imagining: a scientific experiment that would allow her to connect her brain to a “Brainternet” and become unbeatable. Bonus: the suicidal headaches that had plagued her all her life would cease.

But nothing comes without a price, and this connection would give others access to family secrets Yinyin has sworn to protect. Secrets that, at large and in the wrong hands, could be a very dangerous.

Fans of the legendary cyberpunk novels and gritty sci-fi thrillers of William Gibson and Stieg Larsson will be captivated by this new techno-thriller–a fast-paced blend of action, neuroscience, spirituality, and martial arts.

“A superlative new novel by one of Brazil’s most innovative writers. A mesmerizing clash between Eastern and Western beliefs about mind and body.” —Bruce Dean Willis, literature professor, University of Tulsa

“An interdisciplinary brewing of ideas and imagination, packed with futuristic brain science tech, martial arts action, and Asian culture.” — Professor Paul Li, author and faculty in cognitive science, UC Berkeley
