One must always maintain one's connection to the past and yet ceaselessly pull away from it. To remain in touch with the past requires a love of memory. To remain in touch with the past requires a constant imaginative effort.
The Past -- the dark unfathomed retrospect! The teeming gulf --the sleepers and the shadows! The past! the infinite greatness of the past! For what is the present after all but a growth out of the past?
What you've done becomes the judge of what you're going to do especially in other people's minds. When you're traveling, you are what you are. People don't have your past to hold against you. No yesterdays on the road.
