A number of friends and colleagues over the course of my career have been influential in my success as a thought leader and trusted adviser. Their continued support and encouragement made it possible to write this book.

I also want to thank my SAS editor Stacey Hamilton and publication advisor Lou Metzger for their continued support and help with the editing and distribution of this book. Their encouragement to write the first book ultimately led me to write this third book. Their input and suggestions have enhanced the quality of the book.

Most of all, I want to thank my wife, Cheryl, for keeping the faith all these years and supporting my career. Without her support and encouragement, I would not have been in a position to write this book.
