I loved the book Alchemist. It is a short book of a journey of a Shepard who is set off to pursue his dreams and in doing so he finds himself. The book is full of invaluable lessons of life and therefore I don't think of this book as a novel but a self development book for sure. If you haven't read it, I urge you to read it. If you have read it already, read it again.
From all the invaluable life lessons Paulo Coelho has mentioned is this book beautiful, the one I am definitely taking home is that there is no use of one's knowledge unless applied- it is important to live it, experience it and put into action, otherwise knowledge is useless. In the journey of life where we live by what we know, is the only way we can become better versions of ourselves and have a meaningful existence. Practical living is critical to our learning as growth.
So to all the dreamers out there, go realize your dream. If your dream it, it's also your 'responsibility' to go get it !
