I bought this book a few years ago (5 IIRC). I started skimming it and got pretty sad about the things one supposedly had to do to make it. Then I lost the book a few days later when I left it on a flight. I took it as a sign; I didn't bother going to go to lost and found or buy another copy. I wonder if I did the right thing. :)
