This book is a story that teaches the principles of overcoming fear.
Hidden in the story is a variety of principles both scientific and psychological.
Everything we do is because of feelings. We do things to get feelings, riding a roller coaster, jumping out of an airplane or falling in love. We do things to avoid bad feelings, the man who becomes successful to show his father he is not a failure, or the person who becomes an addict because they want to escape their feelings.
The real key to success in life is to create whatever feelings we want on demand and to consciously change feelings into something that benefits us.
This book is about neuro-engineering, the ability to change our feelings through physical and psychological methods.
