Epictetus presents challenges as revelatory mirrors rather than merely burdensome obstacles. Difficult situations strip away pretense, comfortable illusions, and social masks to reveal our true character - our genuine resilience, deeply held values, and actual capacity for virtue under pressure. In prosperity, anyone can appear wise and virtuous, but adversity reveals who we really are beneath the surface. These moments of testing are not punishments but opportunities for authentic self-discovery and character development. They show us where we are strong and where we need to grow, what we truly value versus what we merely claim to value, and whether our philosophical principles are real convictions or mere intellectual accessories. Difficulties are the gymnasium of the soul.
