What is the meaning of life? 
Yes, the book begins with such a chapter. 
It attempts to explore the meaning of life in different ways. 
I understood business, I understood technology, I understood parallel universes, I understood machine learning; every day I learn and know so many things, but I just don't understand life. 
That's why there's a huge black hole of emptiness within us. 
To fill this inner void, the initiation of the book "Mastering Your Life" is to transform the world of thoughts about life.
