This book is an inspirational shot of energy, especially useful for frontline employees who engage directly with your customers. The stories are fresh and emotional. The principles are meaningful and true. And the overall experience is one of empowerment and possibility.
If you are a leader, I recommend you buy this book for your team. Having a discussion together on this could elevate their commitment to exceptional service.
Bonus: I read this in audiobook format and the author did one of the best jobs of audio-narration that I've heard (and I've heard thousands, literally). I highly recommend that format for this book.
