Input: This book was a big disappointment. It lacks depth, has no new information, and is not entertaining - in fact, I'm embarrassed to tell my friends I own it. The only thing it accomplished for me was, ironically, making my job more difficult. As it turns out there are many "self-help" books about finding your true passion that offer much more, as well as numerous websites devoted to this subject.
Output:
Bad review
