A worthwhile piece of advice from John Updike for aspiring writers:
Try to develop actual work habits and, even though you have a busy life, try to reserve an hour, say, or more a day to write. Very good things have been written on an hour a day. . . . So take it seriously, set a quota, try to think of communicating with some ideal reader somewhere. . . .
Don’t be contentious to call yourself a writer and then bitch about the crass publishing world that won’t run your stuff. We’re still a capitalist country and writing, as some would agree, is a capitalist enterprise… It’s not a total sin to try to make a living and court an audience.
Read what excites you… and even if you don’t imitate it, you will learn from it. . . .
Don’t try to get rich. . . . If you want to get rich, you should go into investment banking or be a certain kind of lawyer. On the other hand, I like to think that in a country this large and a language even larger, that there ought to be a living for somebody who cares and wants to entertain and instruct a reader.
