With love, this book is dedicated to my father, Duckhee Lee, who has taught me diligence and hard working; to my mother, Younghee Lee, who has taught me how to lead and trained me to become tough; to my one and only sister, Katelyn Jongmee Lee; to my dearest daughters, Sophia Koen and Charin Lee, who constantly bring me happiness; and to my wife without whose support I would not be at where I am.
