Acknowledgements

Thanks a lot, Lord Almighty, for giving me patience and perseverance to accomplish the task of writing my first book. It was a long journey yet every moment was exciting and forward-looking. I extend my gratitude to my family, friends, colleagues, and all those who have supported me in my endeavor. They have been a source of constant motivation and kept me going in all phases of the task. The book could not have taken the current shape without the support of my husband, Sandeep who spent time discussing the content of the book and suggested some key features for the book. Thank you, my son, Navya—a strong pillar of my life-despite being a small kid, he exhibited a very understanding attitude and has always made me grow stronger. Navya, Daivya, and Neetigya’s affection has always been a de-stressor. I express my gratitude to my in-laws, who bestowed their blessings and best wishes for achieving the task.

I am indebted to my parents whose unconditional love and support have always been there in whatever I pursue. The faith and confidence that my father showed in my efforts could only make this accomplishment possible.

I would also like to thank Pearson Education and the editorial team at Pearson for their constant support throughout the process by publishing this book.

I would also take this opportunity to thank my students who provided specific comments and feedback on the manuscript. I would also like to thank Dr TV Rao, who despite his busy schedule wrote a foreword for the book.
