That is what is marvelous about school, she realized: when you are in school, your talents are without number, and your promise is boundless. You ace a math test: you will one day work for NASA. The choir director asks you to sing a solo at the holiday concert: you are the next Mariah Carey. You score a goal, you win a poetry contest, you act in a play. And you are everything at once: actor, astronomer, gymnast, star. But at a certain point, you begin to feel your talents dropping away, like feathers from a molting bird. Cello lessons conflict with soccer practice. There aren't enough spots on the debating team. Calculus remains elusive. Until the day you realize that you cannot think of a single thing you are wonderful at.

But illness does not always write itself upon the body, the sickness I search for is hidden deep within the brain. Sometimes it rises to the surface. Sometimes the face betrays what the body conceals. But there moments, these betrayals, last no longer than an instant. They come, they go, they pass over the patient, darkening and brightening his face like clouds gusting over a meadow. How is it possible, then, to tell what he is suffering when the visible signs of his inner disorder appear so fleetingly upon his face?
