My sincere thanks to all the people who directly/indirectly taught, guided, supported, and advised me to become a consultant. I am doing my best to improve myself. This acknowledgment is for the people who have made a massive impact on my career. I'd like to thank all of them as I cannot thank them enough.

My older brother Ramy, who is my inspiration, gives me his time, effort, daily advice, coaching, and leadership. He always gives me support and encourages me. He is my mentor. Ramy put me on the information technology track and gave me the chance to choose which gate I will pass through. He helped me to finish my college and convinced me to attend the first e-commerce seminar in the Middle East; that was the first spark. I consider Ramy as my source of energy.

I cannot forget my mother's support and her prayers for me.

Also, my wife sacrificed so much of our personal life during the development of my career, and I cannot thank her enough for that.

Chandru Shankar, an EMEA and LATAM ERP lead with Microsoft, has given me a lot of motivation and support during my career. I can always approach him for advice or to share ideas. I am very proud to meet a person like him and consider him as a family friend. He is my career role model.

I dedicate this book review to the memory of my father and my uncle Hamza; both of them invested in my brother and me the seeds of concepts and beliefs, and now we are harvesting them. My father always said to me, "I believe in you when you say you can do; you can achieve more than what you target; just focus", and my uncle Hamza said to me after my graduation, "You just met your lifetime teacher who will guide you through your entire life".
