Dedicated to my love, Elina, and my girls, Diana, Victoria, and Alisa, who taught me many new things about time optimization and resource management. They also finally showed me the real meaning of the idiom herding cats.

Michael Rosenblum, Verona, New Jersey, 2014

To the best part of my life, my family. Ileana, my wife, who helps me to be a better person and father. Her vision and dedication to all of her endeavors is an inspiration to me. To my son, Robert. I love to see him learn and grow. His wit, charm, and intelligence are a constant source of happiness for me.
