As always, this book is dedicated to my wife, Grace; as well as my children, Dr. Kaitlin Ryan-Smith and Michael Ryan; my son-in-law, Daniel Smith, and my granddaughter, Riley Grace.

It is also dedicated to Russell Siller, an incredible teacher and an extraordinary human being, taken from us too soon. His influence on me as a young man cannot be overstated.

This book is also a thank-you to all those who have supported my earlier efforts—this one’s for you!
