First of all, we would like to thank all our colleagues and friends for sharing our happiness at the start of this project and following up with their encouragement when it seemed too difficult to complete. We are thankful to all the members of Scrivener Publishing, especially Martin Scrivener and Phillip Carmical, for giving us the opportunity to write this book.

We would like to acknowledge and thank the most important people in our lives, our parents and partners, for their support. This book has been a long-cherished dream which would not have been turned into reality without the support and love of these amazing people, who encouraged us with their time and attention. We are also grateful to our best friends for their blessings and unconditional love, patience, and encouragement.
