The writing was engaging, and I enjoyed reading the stories about people who had found ways to combine passions and finances. Overall, the book left me discouraged since it drove home the steep slope I would have to climb to retrain for a different field at this point. I did pick up some ideas about fields that I wouldn't have considered in the past, but I felt frustrated by the lack of practical advice with regard to giving up one path for another without shirking my responsibilities to my family.
Three-point-five. I think this book would be especially useful for people interested in going into environmental, non-profit and "sustainability" work. Even without that focus, however, it provides a lot of helpful reframings, and, I found, a generally freeing and empowering approach to re-orienting oneself in times of transition.
