These science-backed pillars of resilience work in the battlefield and the boardroom. Resilience is not an inherited trait. It is a disciplined practice—a way of showing up that is cultivated over time through deliberate training of the body, mind, and spirit. In high-stress environments, whether on the battlefield, in the boardroom, or in the quiet turmoil of daily life, the ability to remain steady amid volatility is what separates reactive living from intentional leadership. What many discover, often through hardship, is that resilience is less about bracing against impact and more about widening the internal space between stimulus and response. That space—Viktor Frankl called it the foundation of freedom—allows for clarity, intentionality, and courage.
