" It is six A.M., and I am working. I am absentminded, reckless, heedless of social obligations, etc. It is as it must be. The tire goes flat, the tooth falls out, there will be a hundred meals without mustard. The poem gets written. I have wrestled with the angel and I am stained with light and I have no shame. Neither do I have guilt. "
