When I first got this book I was not impressed. Its simple paperback structure lead me to believe I overpaid for knowledge that I could surely get from the internet. Ha I’m glad I didn't stop on the first page. Once I started reading, or at times the book seemed to be reading to, 'me.' Knowledge poured into my mind I tried to resist thinking that my mere mortal mind could handle it all. The book helped me with that, or as I call the book now, 'precious.' Precious showed me how to not only optimize computer science combinatorial logic. It optimized my life. I now have a super-model wife and a 5 year old who plays the violin at concert level. None of this would have been possible without my purchase, I mean investment in this book.
