This is really a great book. For a layperson like myself who's looking for an intelligent, informed discussion of perfectionism, and suggestions for how to find relief from its more negative aspects, "When Perfect Isn't Good Enough" strikes an excellent balance between an overly technical professional text and the all-too-common self-help book that's too high on fluff and too low on content. This book - which I very much enjoyed reading - is packed with useful information (and good exercises) on how to break free from patterns of perfectionistic thinking and behavior; and it contains what I thought were interesting and insightful discussions on how perfectionism ties together with depression, anger, social anxiety, worry, and other "not so pleasant" dispositions that many of us realize to some degree or other. I found the book quite helpful, and expect to get a fair bit more out of it. Antony and Swinson are clearly experts. Of all the books I've read or looked at on the topic, this one's the best. I highly recommend it.
