Never before in history have so many humans suffered from depression, anxiety, and stress. The World Health Organization estimates that more than 300 million people struggle with depression - equivalent to 4.4 percent of the world's population, with even more suffering from anxiety and stress. Therefore, it is critical to understand why those of us, especially in prosperous countries with high living standards, continue to get sick, particularly due to work-related stress. Studies have consistently shown purpose and meaningfulness to be essential for performance and mental health in a work place. As a result, human beings are increasingly seeking purpose and meaning in their life. Key to unlocking meaning is the idea that we are all one human being, regardless of the context. It is the purpose of this book to ensure we stop separating our persona into a working human being and private human being, and instead see ourselves as one human being, with one life in one lifetime.
