What Marley captures here isn't optimism about hidden reserves, but rather the peculiar arithmetic of crisis: desperation doesn't *create* strength so much as it strips away the permission to doubt yourself. When a single parent works three jobs after a spouse leaves, or someone faces down a diagnosis alone, they're not suddenly discovering untapped potential—they're operating without the luxury of hesitation that more comfortable circumstances allow. The insight's sting lies in recognizing that strength was always available, but choice required alternatives we no longer had. Most of us move through life never calling on our deepest capacities simply because we could settle for less.
