You may have recently heard Dr Lizzy Bernthal speak at the Chamber’s Health and Wellbeing Forum, where she shared insights on resilience, confidence and what leadership really means in today’s workplaces.
Lizzy, founder of Release Your Potential Ltd, believes strongly that leadership is a behaviour, not a job title. It is something that shows up in everyday conversations, decisions and actions, particularly when pressure rises.
This philosophy sits at the heart of her new book, The Courage to Be You: The Key to Unlock Your Resilience and Confidence as a Leader, which went straight to No.1 Amazon Bestseller in five categories on launch day (17 February 2026).
Before founding her business, Lizzy served 25 years in the British Army, reaching the rank of Lieutenant Colonel and leading healthcare teams across 18 countries, including operational deployments to Afghanistan. Those experiences, combined with her PhD research in resilience, shaped her understanding of what allows leaders and teams to perform well in challenging environments.
In The Courage to Be You, Lizzy explores how leaders can move beyond self-doubt and the pressure to appear perfect. Instead, she encourages leaders to develop resilience, communicate with confidence and lead with authenticity.
The book offers practical insights into how leaders can clarify their purpose, navigate difficult conversations and remain calm and focused when facing uncertainty.
At its core, the message is simple: when leaders have the courage to be themselves, they create workplaces where people feel confident, valued and able to perform at their best.
The Courage to Be You is available on Amazon in paperback and Kindle.
