I would like to dedicate this book to my late grandfather, my mentor, and my teacher—Dr. Syed Enam-ul-Haque. He always encouraged and inspired me to share knowledge and learnings with others, and it was with him that I started working on our first book. I want to thank my lovely wife, Sameera, and my children—Omer, Ammaar, and Emaad—for their love and their strong support of me while writing this book. I would also like to acknowledge the support of my parents. I couldn’t achieve what I have without their encouragement and the guidance they continue to give through their wisdom.

To my wonderful parents, Khurshid and Shakila, who instilled in me the value of hard work and perseverance from a very young age; to my wife, Sara, my north star who inspires me to be a better person every day; and to my kids—Aleena, Rayan, and Faaris—who motivate me to do my part in building a better tomorrow.
