Forgive me for rating a respected book so poorly. If your quest is to discover why certain disciplines are needed, then ignore what I have to say. This book delivers. If, on the otherhand, you are going to buy this book with the expectation that it will move beyond expressing the need, you will be disapointed. If you are looking for help in developing these disciplines in your life, you will not find it here. This book is not about "how", only "why". Which question are you asking?
