At its core, resilience is about adaptability. Life is filled with ups and downs—personal losses, professional setbacks, and societal challenges are all part of the human experience. What distinguishes the resilient individuals from the less resilient ones is how they respond to these challenges. Rather than succumbing to despair or defeat, resilient individuals view obstacles as opportunities for growth. They embrace change, recognize that discomfort often precedes personal development, and remain open to learning through their experiences.
