This book is little more than a (mercifully) short autobiography of an arrogant and misguided know-it-all. Think of the most self-centered and obnoxious person you know, and then ask yourself if you'd want to read a book they'd written about their own life. To me the book was hard to read because I found the author's personality so annoying. Even when he admits to making mistakes, he strongly hints that it was because he was more intelligent or more ethical than everyone else around him.
Also, throughout the book, he kept blowing the trumpet and waving the banner of his Liberal politics. He apologized a few times for being born a white male, but then he used it as an excuse because, he says, our society teaches all white males that they can do anything they want to do in life. And he feels the pain of all who are not white males because, he says time and again, that our society is, apparently without exception, sexist, racist and homophobic. In one overwrought metaphor, he advises that we should all strive to be like Rosa Parks and sit down on the bus of life and name and claim what is ours. Huh?
Palmer has, for now, concluded that his vocation is to be a writer. Based on this book, I can't agree. Therefore, I cannot recommend a book on vocation written by someone who has apparently chosen the wrong vocation.
If you're looking for a book that is truly full of wisdom, get Thomas Merton's, No Man Is An Island. The entire book sings, and it contains an excellent chapter on vocation.
