Once again to my wonderful family: David, Michaela, and Cassandra.
And to the readers who have purchased all three editions of this book.
To my wife Navya and my son Abhinav for their love,
To my family and friends for their support,
To my teachers and mentors for their guidance,
And to my patients for their inspiration.
To my wife Natassa and my sons Yannis and Aristomenis for their love and unlimited support,
To my teachers for their mentorship and guidance,
And to my patients with endless gratitude.
