People no longer write letters. Lacking the leisure, and, for the most part, the ability, they dictate dispatches, and scribble messages. When you are in the humor, you should take a peep at some of the letters written by people who lived long ago.
All good writing is built one good line at a time. You build a novel the same way you do a pyramid. One word, one stone at a time, underneath a full moon while the fingers bleed.
