Acknowledgments

I am grateful to my enthusiastic son, Aarav Bhargava, and my lovely daughter, Ahana Bhargava, for giving me the time needed to write this book. It was a great effort. I am also grateful to my mother, Dr. Urmila Devi, who has been an unceasing source of inspiration. When my mind grows resistant to trying something new, I can always count on my elder brother, Vijay, whose positive energy always keeps me going.

Thanks also go to the entire team of people supporting me in accomplishing this milestone—a journey that I began two years ago. I do not want to write a book for academics, but would like to share the complete practical experience I have attained over the years.

My next big thanks go to my wife, Vandana, for managing all her time with our kids when I was not able to and also for lending her time to editing this book. It was a pain and pleasure to go through the first complete edit. Her performance has been excellent throughout this process, and without her, producing this book would not have been possible.

I would be remiss if I did not acknowledge my past and present friends who kept me motivated throughout the years of preparation needed to accomplish this dream project.
