The term "calling" is rather misleading: it implies something unequivocal and unmistakable, like Moses hearing a voice from the burning bush or Paul being knocked off his horse. But, more often, it's a whisper you have to strain to hear, or a series of little signs you'll overlook if you aren't paying attention. Levoy's book is less a how-to guide than a meditation on the nature of callings and how to listen for them. He uses many examples from his own life, but, to his credit, he doesn't take himself too seriously or pretend that he has The Answer to anyone's questions about the meaning of life -- even his own. And his subjective insights are balanced by plentiful examples from the experiences of others. His anecdotal style, his heavy use of quotations, and the circular structure of many chapters might frustrate a reader looking for direct guidance, but I found the book thought-provoking and intuition-stimulating. It's the sort of book you can pick up at any time, flip through, and find a paragraph or a chapter that sets off new sparks in your mind. My one complaint is that he often isn't specific enough about the source of a quotation -- e.g., "Goethe wrote ..." is NO help at all with the author of such bagatelles as Faust, Parts I and II! Otherwise, I thought his reference section offered excellent suggestions for further reading: you can pick a quotation that resonates with you, and follow it up with more of that author's writings. Finally, his writing is a great pleasure to read -- it's fluid without becoming monotonous, and well expresses the twists and eddies of his or his subject's thoughts. I enjoyed the book thoroughly, and plan to reread it.
