Each of our small group bought the leader kit due to its phenomenal sale price. We studied this over the summer and this allowed everyone to keep up with the videos even if on vacation. We all agreed that if you will put the work into answering the introspective questions in the workbook, you will emerge a much more enlightened person at the end of the study. No one wants to give their kit away because they want to keep it for future inspirations!
Our church is using this as a Sunday School class curriculum for six weeks. The workbook has some good questions and we have enjoyed the participation the book has elicited. The hardbook book is an easy read and has a lot to say. As the leader of the class, I do wish there had been in paperback form a leader's guide.
