The first printing of this book includes two attribution errors, which will be corrected when the book is reprinted.

On page 4, the text "Each of us struggles every day to define and defend our sense of purpose and integrity, to justify our existence on the planet, and to understand, if only in our own hearts, who we are and what we believe in" is a quotation from Steven Pressfield’s The Warrior Ethos (New York: Black Irish Entertainment, 2011), 10.

On page 131, the text "the ability to understand, discern, appraise, and manage the complexities of specific situations" is a quotation from Melvin Rogers's The Undiscovered Dewey (New York: Columbia University Press, 2009), 62.

I apologize to these authors for the oversight.
