How strange it is to be never at rest, and never satisfied, and ever trying after something that is never reached, and to be always laden with plot and plan and care and worry, how clear it is that it must be, and that one is driven by an irresistible might until the journey is worked out! It is much better to go on and fret, than to stop and fret. As to repose –- for some men there’s no such thing in this life… The old days –- the old days! Shall I ever, I wonder, get the frame of mind back as it used to be then?
Charles Dickens to John Forster, April 13, 1856
