"In my own worst seasons I’ve come back from the colorless world of despair by forcing myself to look hard, for a long time, at a single glorious thing: a flame of red geranium outside my bedroom window. And then another: my daughter in a yellow dress. And another: the perfect outline of a full, dark sphere behind the crescent moon. Until I learned to be in love with my life again. Like a stroke victim retraining new parts of the brain to grasp lost skills, I have taught myself joy, over and over again."
