First and foremost, I would like to thank my wife, Ene, for her support throughout my career and in writing this book. She has been my inspiration and motivation for continuing to improve my knowledge and helping me move ahead in my career. She is my rock, and I dedicate this book to her. I also thank my wonderful children, Femi, Lara, and our new addition, Temi, for always making me smile and for understanding on those days when I was writing this book instead of playing games with them.

I would also like to thank my book reviewersOpeyemi Akinjayeju, who is a dear friend of mine, as well as Louis Hnault and Carlos Marinfor their invaluable feedback and input toward the completion of this book. Lastly, I would like to thank my parents, George and Katie Anthony, for instilling a strong work ethic in me from an early age.
