From my Amazon.com review of Covey's 8th Habit:
Poorly conceptualized. Those are the only words to describe the Eighth Habit, a lengthy tome based on one principle that promises to be the "holy grail" of principles, but instead feels like a soggy loaf of day old bread. I am a disciple of Covey since 7 Habits first came out; own the CDs and listen to them, even now, yearly. They contain realistic, practical advice (not a "Cheerleader" like Tony Robbins et al) that allows you to integrate seven simple skills into your thought pattern. The Seven Habits are lively with example and crisp in its scope. The Eighth Habit, however, is more ethereal, more of a notion as to what the habit of purpose should be than it is a true guidepost on the compass of life (to use Stephen's analogy). Rather than climbing the ladder of success only to find that it is placed on the wrong wall--as Covey so eloquently professed in his milestone first bestseller- this book would preach that it can help you can find "the wall", a true purpose in your life. Therein lies the rub, as the mushy substance of the book does not allow intriguing storylines for example, and the essential notion of the book rapidly becomes repetative and lackluster. I strongly advise those who have not recently read or heard the Seven Habits to review now. For those hoping for a successful Eighth habit, save your money on this book/audio CD and spend it on a trip to the beach, in a sunset, look to the sky and ask, "What am I all about, (insert your god or goddesses' name here)?" and think.
