"Fantastic!"
This book is great. You don't need this book to tell you "how to" be indispensable, but it will come naturally once Seth Godin has INSPIRED you to be indispensable! It's about how to approach and execute your "job" functions so the net result of your performance day to day expresses who you are and what you can be. You are unique and indispensable, and deserve to experience and enjoy all of the gifts that you can give and receive through your life's work. I am encouraged, inspired and optimistic and have been recommending this book to everyone.
Plus it is read by the author, who miraculously does not have an annoying voice.
