This is an extraordinary story about optimism, hope, courage and perseverance. It is about finding out what is our 'mission' in life, about destiny and following our dreams - whenever one wishes something, the whole universe conspires to its realisation. Everything is possible as long as we really want this to happen.
At the first level, the story seems to be very simple, and as Coelho himself said it, "simple things are the most valuable and only wise people appreciate them". But it is by far a very complex story with very deep meanings.
One of the things suggested here is that people who don't dare to follow their dreams, their 'Personal Myth', will have a superficial and empty life.
It is also about being courageous to meet your destiny, to dare making your dreams come true and following the road that has been made for them, and find God while searching for their destiny and their mission on earth.
Another important issue in this book is finding your soul-mate and love - the core of existence and creation. When we are in love we try to improve ourselves: "I love you because the whole universe conspired for me to come close to you."
I think this book can be enjoyed by everybody, because we all find ourselves in Santiago, the main character of the book - we all have dreams, desires and perhaps some us dont have the necessary courage to follow our dreams - and courage is the language that helps you most in understanding the world.
I recommend this book to everybody who thinks that life is still beautiful and even to those who believe the opposite - Im sure it will make you change your minds.
