Double your dating

Yeh, this is a kind of ad of David D'Angelo, but I won't infract you for it. I assume you are asking because you are a guy who has problems picking up women and want to increase your chances. If you want an honest opinion, I don't think there's anything new D'Angelo, Mystery or Style are going to teach you. They will talk some strategies, which will work only in a small amount of situations. The best you can hope to get out of this "Educational material" is more self confidence to approach women, which 9 out 10 is all that you really need to increase your chances. So look at it if you must, but take it with a grain of salt.
