Just finished reading it, if you haven't, it is worth the time. Despite the fact that it is ~450 pages, it is a very quick read and I got through it in just a few days. There were many things that he discussed, but these are the top three that changed my game and my approach to women. Hope they help.

1) Being alpha is about your inner verification; it is not how you act on the outside. Though being self-verified will cause you to act alpha, it is much more subtle and goes deeper than just your behavior. It is truly your entire perspective on yourself. I used to think about how I should act in situations in order to be the alpha male. Now I am just extremely comfortable with myself in any situation and these thoughts disappear. I am allowed to be friendly and warm towards anybody because I am not so concerned with trying to look alpha in front of the ladies. This was huge for me because now I feel self-verified in any given situation and it allows me to be comfortable all the time. It is no longer just a social pattern to look attractive.

2) The best way to pick up women is to have something better to do than pick up women. Truly, take this to heart. Before "The Game," I was definitely thinking about women and PUA material too much. I felt like it was making me less interesting of a person because I was devoting so much time to this one activity. If you can put all this stuff on the back burner, you will open yourself up to more that life has to offer than just picking up women and you will live a more interesting and fulfilling life. Ironically, this will allow you to be more attractive to women.

3) Stop worrying (stop being a bitch). I used to try to be a stand-up, respectable guy all the time and in front of all women. If I was gaming one girl, I would try my hardest to not game other girls in front of her and I would try to keep these sets completely separate. Now I dgaf and do whatever I please, short of being a complete dickhead to women. And because of this if a girl I am trying to game sees me getting attention from other women, she will see that I am socially valuable and have already been approved by other women. This will make her want me, or want me more. Not to mention that she will get jealous and start fighting for my attention. So if I'm chatting up one girl and move on with plans of continuing my game on her, I won't be afraid of making out with another girl in the vicinity, and this completely works to my advantage. At first, I thought this would ruin my chances with girls that I had been gaming when they saw me mackin on another girls, but no. They see that I am valuable, confident, and do what I please. Completely did not ruin my chances with them.

So there you have it, my three favorite concepts, in my own words. Hope it helps some of you not just with women, but with living a happier life.

PS- Beware the shit-tests. They are so much more obvious to me now and no matter what, never lose face and give in to their heckling. If you can spot the shit test and show no cracks in your facade of awesomeness, you're in.
