I've just finished The Servant Leadership Training Course on CD.
There isn't anything new in this book and if you've read and understood the other popular books in this area then this will just be a repeat.
However, having this information repeated to you on a regular basis is very useful. And having it repeated from a different point of view is even more useful. For that reason I enjoyed it. The first quarter of the book was a bit redundant but the rest was good.
I didn't care much for the author's condescending tone and attitude but if you look past that you'll see that the material he's presenting is of value.
