This is a great book for aspiring writers as well as established writers looking to branch out into new areas. A lot of writing books seem to be by a novelist writing only about novels, by a screenwriter writing only about screenplays, etc., but Wolff explores both of those genres, as well as non-fiction books, magazine articles and more. He assumes you're serious, and while he doesn't fill you with delusions of grandeur, he doesn't insult you by selling some fantasy of instant riches, either. He makes it clear that writing for a living requires dedication and hard work, just like any other career, and then he shows you how to go about making it happen.
