“Writing, to be effective, must follow closely the thoughts of the writer, but not necessarily the order in which the thoughts occur. This calls for a scheme or procedure. In some cases the best design is no design, as with a love letter, which is simply an outpouring, or with a casual essay, which is a ramble. But in most cases planning must be a deliberate prelude to writing. The first principle of composition, therefore, is to foresee or determine the shape of what is to come and pursue that shape.”
