I noticed his stuff is all about how you think about it.
If you are closed minded and think that you know all about how women and social relationships work with them you will not get anything out of his material. For example I have a friend I introduced his material to and he was just like "yeah right, I am not going to go make an a$$ of myself to impress a woman" and I was like "what part of this stuff works don't you understand? you arent making an as$ of yourself to women when you do this, you are making yourself more attractive"
Another thing is you have to believe you can change the way you are in terms of your personality. Again, if you don't think you can be more outgoing or sociable or have more of whatever it is you're lacking and no amount of working on it will help you, then again this material isn't for you. That same friend who said the above also said that personalities can't change and he isn't very outgoing or direct with people (shy type) so he will never be able to be anything different.
So if you're attitude is anything like my friend's, foget about it, just become a priest or subscribe to porn because thats probably going to be all you'll get with that kind of attitude.
On the other hand if you are willing to let go of some ideas that you've been conditioned with and see things for what they are in reality then this stuff is for you.
When listening to his Double Your Dating lecture thing I caught myself going "yeah I notice that!" or "that's totally happened to me!" and other things like that in my head, cause I could see where he's going with this.
I can recognize bad advice right away, or advice that doesn't conform to reality. And DeAngelo's stuff was RIGHT ON how it is, I don't think a single statement he said was off in any noticeable way where it just struck me as "no way, that's a lie" or "no way, thats not how things are"
To my friend though who has this whole other worldview of women (and hasn't ever had a gf himself) his stuff seemed like total b.s. because he thought he knows better.
