Stamina is the capacity to sustain yourself through the long stretches of effort that meaningful lives require. It’s not intensity or the ability to push endlessly, but the steady vitality that allows you to continue without losing yourself along the way. Stamina develops when robustness helps you remain whole under pressure, flexibility allows you to adapt without breaking, and each step teaches you that progress is built gradually. It reveals itself when steadfastness keeps you committed, perseverance keeps you returning, and endurance carries you through what takes longer than expected. By the time you arrive here, resilience no longer feels like something you do, but something you have become.
