I found this book to be an excellent resource and one, I'm sure, I'll return to again and again. Although it's designed to be read one part per week over the course of a year, I have actually only spent 3 months working through it -- this time! Full of quotes, food for thought, ideas that really grab you, practical suggestions, and questions to ask yourself, this is a spiritual growth book that could really be helpful in simplifying life, considering what's really important, and journeying toward a "you" with which you will ultimately be more satisfied.
If you belong to any groups that meet together and begin with some type of opening icebreaker or other exercise, the individual segments are short enough and, IMO, adaptable enough that they would provide great resources for that type of use.
In short, I loved it!
