"Why do you never find anything written about that idiosyncratic thought you advert to, about your fascination with something no one else understands? Because it is up to you. There is something you find interesting, for a reason hard to explain. It is hard to explain because you have never read it on any page; there you begin. You were made and set here to give voice to this, your own astonishment. "The most demanding part of living a lifetimes as an artist is the strict discipline of forcing oneself to work steadfastly along the nerve of one's own most intimate sensitivity." Anne Truitt, the sculptor, said this. Thoreau said it another way: know your own bone. "Pursue, keep up with, circle round and round your life....Know your own bone: gnaw at it, bury it, unearth it, and gnaw at it still."
