"Writing is alchemy. Dross becomes gold. Experience is transformed. Pain is changed. Suffering may become song. The ordinary or horrible is pushed by the will of the writer into grace or redemption, a prophetic wail, a screed for justice, an elegy of sadness or sorrow. ... There is always a tension between experience and the thing that finally carries it forward, bears its weight, holds it in. Without that tension, one might as well write a shopping list."
