In my own worst seasons, I've come back from the colorless world of despair

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 someone recovering from a stroke, retraining new parts of the brain to grasp lost skills, I have taught myself joy, over and over again.

—Barbara Kingsolver, "High Tide in Tucson"

(This might not sound like a writing quote, but I think this is also how we teach ourselves to see, over and over, and how we write.)
