Leading On Empty
If you are a leader in a church you need to do yourself a favor and go buy this book. You're not a leader? Go buy one and give it to a leader near you.
This book was like a good punch in the face. The kind that reminds you that you don't like getting punched in the face and you need to do something in order to prevent getting punched in said face in the future.
I'm also going to tell everyone to buy this book. Brad bought it, and he's so awesome that you should just do it to be like Brad. Or to be like Mike.
