There are plenty of good reasons to become a writer—excepting of course a desire for money, fame, or respectability.
In “Phi Beta Football,” a football-season essay for the New Yorker about his childhood watching Princeton football games, John McPhee identifies another superb reason to devote one’s life to the written word:
…on a November Saturday of cold, wind-driven rain—when I was about ten—I was miserable on the stadium sidelines. The rain stung my eyes, and I was shivering. Looking up at the press box, where I knew there were space heaters, I saw those people sitting dry under a roof, and decided then and there to become a writer.
