I read this book in my first year at Uni. It might sound a bit clichéd; but really had quite a profound effect on my outlook on life, and also the way in which I approached pretty much everything (and everyone) from then onwards. And not in terms of a new method or process or formula, but in terms of critical thinking and the spectrum between emotional and rational, romantic and classic, creativity and logic etc. etc. It was heavy going at times, and the narrative, complex but the reward , for me at least, was everlasting.
