Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.
If I go into a sandwich shop or anywhere that features 'Today's specials' on a chalkboard more than 10 feet away, I have to ask for a printed menu. I smile at people I don't know on the street and ignore those I do. When at home, I often find myself grabbing my 'back-up' glasses to search for the better-loved pair I have left on top of my dresser.
Construed as turf, home just seems a provisional claim, a designation you make upon a place, not one it makes on you. A certain set of buildings, a glimpsed, smudged window-view across a schoolyard, a musty aroma sniffed behind a garage when you were a child, all of which come crowding in upon your latter-day senses -- those are pungent things and vivid, even consoling. But to me they are also inert and nostalgic and unlikely to connect you to the real, to that essence art can sometimes achieve, which is permanence.
