Quintessentially the best book ever written on startups. If you don't read this in your lifetime you really have no idea what you are missing out. Thiel is a visionary and a philosopher. Most of his ideas if adopted by the industry could change the world exponentially. There is a lot of depth behind what he writes and you need to knock your brains out to fully comprehend the meaning behind his words. I could read this book as many times possible in this mortal lifetime and still not be bored. Its Ulysses devoid of the complexity. Thiel could be perhaps be termed as the 'Nietzsche' of this century.
