Dedications

“To fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy’s resistance without fighting.”

—Sun Tzu, the Art of War

From David:

This book is dedicated to my wife and best friend in life, Lisa, whose love, encouragement, and support continue to drive my passion to learn, achieve, and serve; to our two boys, Will and Christian, who have an unending curiosity to learn, grow, and challenge the norm; to my extended family for their support, encouragement, and inspiration all these years; and finally to my fellow soldiers (present, past, and future) for their selfless service, integrity, honor, pride, and drive to do the right thing to protect us all—God Bless!

From Odunayo:

This book is dedicated to God for his many blessings; to my loving wife, Aramide, who always gives me great encouragement and support, especially as she did during the writing of this book; and to my parents, who have continually encouraged my brother, sister, cousins, and me and our families, in everything we’ve done. Also to the loving memories of my aunt, Olayemi Akere, and cousin, Korede Akindele, who were supportive and instrumental to my many successes.
