Reviews: From Page to Practice – Readers Voices on 6 Leadership Skills

6 Leadership Skills is more than a book — it’s a practical guide, a spark for reflection, and a source of renewed confidence.

Leaders across industries have shared honest insights and real experiences after reading it, describing how its lessons translated into meaningful change in their leadership and daily work.

Their voices speak to the book’s power to inspire both personal growth and tangible results.

  • Der Austausch mit meiner Kollegin Eleonora Bonacossa war so ein besonderer Moment, denn sie steht für eine Form von Führung,
    die Herz und Verstand verbindet – und Menschen befähigt, das Beste in sich und anderen zu wecken.
    In ihrem Buch beschreibt sie sechs zentrale Skills, die moderne Führung menschlicher, wirksamer und nachhaltiger machen.

    Die 6 Leadership Skills
    1.⁠ ⁠Zugeben, nicht alle Antworten zu haben
    Stärke zeigt sich, wenn du Unsicherheit zulässt – und damit Vertrauen förderst.

    2.⁠ ⁠Proaktives Hören
    Präsenz heißt, nicht nur zu hören, was gesagt wird, sondern auch, was zwischen den Zeilen mitschwingt.

    3.⁠ ⁠Sicherheit geben
    Menschen entfalten ihr Potenzial dort, wo sie sich sicher fühlen, Fehler machen zu dürfen.

    4.⁠ ⁠Wertschätzen
    Echte Anerkennung ist kein Lob – sie ist das Sehen des Menschen hinter der Leistung.

    5.⁠ ⁠Sich kümmern
    Führung bedeutet, Verantwortung für Beziehungen zu übernehmen, nicht nur für Ergebnisse.

    6.⁠ ⁠Ermutigen
    Vertrauen zu schenken ist eine stille, aber kraftvolle Form von Leadership.

  • I have just finished reading your book. I already know that I will read it several more times. It is inspiring! In the end, it’s all about humanity in leadership. I want to lead exactly as you describe in your book, and I would be grateful if more managers and leaders thought the same way.

    We don’t need all the inauthentic ego-driven behavior in leadership. It does no favors to oneself or to employees. With humanity and a sense of togetherness, you achieve so much more!

    Furthermore, I can confirm what you write in the last chapter. Women need to be more encouraged to realize their potential. This is a wonderful task for a leader.

    I work for a large pension fund in Switzerland and lead around 35 people. I directly manage four team leaders, and I would like to give them your book as a Christmas gift, so I would like to order 5 copies of your book.

  • This book was given to me by the author when we met on the Nordic Business Forum 2023 in Helsinki. This is an excellent leadership guide, easy to read, written in accessible language and without waffling.

    The book clearly traces the structure and highlights the main themes. It contains many useful tips and tricks that you can put to work today.

    I would recommend it to all those who strive to be a leader not only at work but also in everyday life. It’s all about humanity, being human means being able to admit your mistakes.

    Preserve the human being within yourself! This simple to the point book helps leaders to decode some of the misconceptions about the leadership skills in today’s dynamic environment.

  • With her breakthrough work, „6 Leadership Skills,“ Dr. Eleonora Bonacossa clearly wants to prove, once and for all, that skills like vulnerability, building trust, and creating emotionally safe environments for employees so they can flourish, really are the key skills that today’s leaders will need to learn, if they are to become the effective leaders of the future.

    In her manifesto, Eleonora Bonacossa explores how leaders who are comfortable in handling vulnerablity, become the cornerstones for establishing powerful, healthy and effective work environments for their whole team, creating an environment where employees and teams feel appreciated and safe to leave the old fears of shame and punishment for mistakes behind
    and instead, feel free to unleash the full force of their immense creativity to help themselves and their teams reach their desired dreams of success.
    It also helps them hold together better during those times of trial and stress, such as many organizations are currently facing in this period of immense transition.

    Eleonora Bonacossa’s „6 Leadership Skills“ is unlike any other book on leadership currently available and is a work that every manager, CEO, or any individual tasked with leading others simply must read and then read again. This is a book that wants to spark a change in leadership, and it will!

  • As a researcher in trust, I have delved deeply into the theoretical foundations of leadership. However, in practice, I often feel overwhelmed – the transition from theory to actual implementation is challenging.
    It was in precisely this situation that mentoring with ARETA became a transformative experience, and their book, 6 Leadership Skills, translated this into a sustainable actionable guide.

    Eleonora is an exceptional mentor. She combines impressive expertise with a profound understanding of interpersonal dynamics. Her empathetic yet highly practical approach makes her mentoring unique.
    Leading and teaching with such heart and intellect – rarely have I met someone who blends these qualities so convincingly.

    Their book, 6 Leadership Skills, effectively combines theoretical insights with practical application. It’s not merely a theoretical work but a clearly structured guide that makes leadership tangible and actionable.
    It offers strategies that are not only well thought out but, above all, directly applicable – a kind of „Leadership-to-go“ for anyone looking to evolve in their role as a leader. Eleonora has called it a „game changer“ for others, and I find her work to be exactly that.

  • Eleonora Bonacossa brings to us the most precise and to the point self help book on the topic of Leadership skills in the form of 6 Leadership Skills to Unleash the Game Changer in You. The book delivers what it says in its title it’s really a game changer for every individual and will really help us build a great and successful team and run it successfully.

    The book as the title suggests talks about 6 skills in 120 pages it talks about things like being a good listener, how to give and receive good feedback, and how we can create a safe and healthy environment for our team. The book teaches us that for being a good leader we don’t need to have all the answers but we should be able to ask for advice and help when we are out of ideas, it helps us to create a healthy work environment where everyone’s point of view is given importance. It also points out that to become a good leader we should be able to create a psychological safe environment where everyone is able to give feedback and learn from each other and many other points are being taught in the book.

    What I liked the most about this book is that it doesn’t talk in circles, it’s always on point and doesn’t unnecessarily increase the number of pages like most Self-Help books do. The language is simple and easily understood and this book can be read by anyone and my recommendation is that everyone should read this as it will definitely help in self growth.

    This will be a great read for self help genre lovers and all of those who want to gain life changing skills by reading books.
