As a pastor who believes in training and discipleship, I have to say that this book is very important. It is written by a guy who has trained many leaders and pastors in ministry. The book is full of insightful and practice ways of staying passionate in your calling. As a pastor I now train and equip potential leaders, this book has been used as a main ingredient in some of my teaching material. Highly recommend this book and his other book called "mistakes leaders make."
