Query: One of the best books ever written !

One of the best books ever written, and I have read lots. Usually in the self help section but this book goes way beyond most writers in its explanation of perception and your placement in society. No believe it and it will come true, no wishful thinking, no Anthony Robins. Clear, Concise and a great insight into the human physique.
