Wallace Stegner said this quote

I am deep in my willed habits. From the outside, I suppose I look like an unoccupied house with one unconvincing night-light left on. Any burglar could look through my curtains and conclude I am empty. But he would be mistaken. Under that one light unstirred by movement or shadows there is a man at work, and as long as I am at work I am not a candidate for Menlo Park, or that terminal facility they cynically call a convalescent hospital, or a pine box. My habits and the unchanging season sustain me. Evil is what questions and disrupts.
