We have invented thousands of complex and difficult machines. We spend long years of learning to use these machines. But how well do we know ourselves? How much time do we spend learning about ourselves? How do we work? What makes us happy? What makes us sad? In this class, we learn: 1. Human machine is the most complex machine that exists on this planet. 2. How does this machine work? 3. What are the buttons that make this machine work? 4. Is it possible to have control over our own buttons? 5. Is it possible to have any say in our life? Any control of our own life? 6. How can we deal with problems? 7. How can we live a long and happy life?
