"For me, the writing life doesn't just happen when I sit at the writing desk. It is a life lived with a centering principle, and mine is this: that I will pay close attention to this world I find myself in. 'My heart keeps open house,' was the way the poet Theodore Roethke put it in a poem. And rendering in language what one sees through the opened windows and doors of that house is a way of bearing witness to the mystery of what it is to be alive in this world."
