I got this book on my kindle for free and think I would have liked the original Personality Plus better. The stories were fun, but I skipped all the workplace stuff because they were all in categories that didn't apply to me. I didn't walk away able to identify anyone else's personalities or my secondary personality which was disappointing. Just an FYI to my friends on here, this is considered a Christian book. I read that the original has tons of biblical references, but this one only had a couple. Overall, fun to read, but I don't feel enlightened.
