I have two doctors, my left leg and my right. When body and mind are out of gear (and those twin parts of me live at such close quarters that the one always catches melancholy from the other) I know that I shall have only to call in my doctors and I shall be well again.
G. M. TrevelyanWhat is easy to read has been difficult to write. The labour of writing and rewriting, correcting and recorrecting, is the due exacted by every good book from its author, even if he knows from the beginning exactly what he wants to say. A limpid style is invariably the result of hard labour, and the easily flowing connection of sentence with sentence and paragraph with paragraph has always been won by the sweat of the brow.
