Et Arcadia in Ego
It could mean "I am always in Paradise" or "I am in death" or "Even in Arcadia is death." I think Thomas Wolfe referred to the first meaning to describe his life in writing, a chronicler of the dead. It has the flavor of someone being in the writing world -- detached and drifting, at the same time mindful of life and death. I'm not sure if the best writing comes from that place. I'd vouch that the best editing doesn't come from there, though. I'm having the devil of a time tying together my reveries.
