Review Detail

My advice is similar to what most everyone else is saying. It was the first book I read, it's what got me into the community. It has a lot of information, definately worth reading.
But it's not nearly as effective as the Mystery Method, in my opinion. David DeAngelo basically gives you a broad set of rules to follow, some tips and maybe even a couple short routines to use, but he has little structure. The Mystery Method gives you an entire structure to use, breaks the entire pick-up into a science.
The other thing, and this is completely just my personal views, but after reading the Mystery Method and the Game, I don't believe being cocky and funny, one of DD mains points, is as effective as he does, especially when your in comfort. Mystery even says cut back the negs when in comfort, something I doubt DD would agree with.
