This was my first ever product, and it was the one that got me into PU.
This helped me SO much. I have no idea where I'd be without it. My life gained value, and the things that he covered were really really helpful. He talks a lot about confidence and dominance. He puts a good bit of theory behind it all, which makes it all make so much more sense. The fact that I learned that confidence was so big of a deal, made my game waaaay more real. Back then I was an 8th grader, and today I am a freshman.
With all that being said, I want to point out the fact that it only reaches so far. All this stuff does not seem so reliable for sarging, as it is very narrow (DISCLAIMER: I have close to zero in-field experience, but I can still assume this). He also lets out a lot of stuff.
Anyways, I find this to be a great beginners book, but i am convinced, that it is not enough. Of course, you can always go out and develop further for yourself, but compared to the bigger systems, it falls a bit short.
