Alvin,
Usually I try not to give personal recommendations on PU gurus, because I'm not affiliated with any of those, and, well, because I'm building my own website, so I'll say I'm the Ultimate Guru above all lol
But since you asked, I will give you my personal recommendation, the guru that strikes most true for me is (...drumroll...):
Juggler
Juggler is on the camp of natural game, which means to develop the attributes that make you attractive to women, instead of relying on structure, routines and so on. Maybe it's not for beginners, but once you know your drill, Juggler is the best way to become a genuinely cool guy.
In fact, I'm a proud defender of this kind of natural game, and my website will be about becoming a cool guy, instead of learning lines and routines. What I'm doing is similar to Kloudiia's blog, but maybe more oriented to a guy's perspective.
For Juggler, there was a compilation of posts for free on the internet. Is a compilation of his best posts on ASF, done by some dude called TheGuru. There was a time that it was for free around, but it seems that since juggler is selling it now on his website, is no longer available (just googled for it but can't find it). You can also get his posts archive at ASF (
www.fastseduction.com).
A guy which is very similar to Juggler is Zan, though Zan does not have much material around.
David DeAngelo is great to start. His books are pretty straightforward, though in my opinion he gives too much importance to "Cocky and Funny", and, while I think it's worthwhile, it's just a partial view of seduction. But it's a good place to start. His smaller books like "Bridges" or "The 8 types of men that naturally attract women" are
pure gold. Is very important to know the distinction between a
lover and a
provider, and the difference between being
dominant and
submissive, in a relationship.
The Venusian Arts Handbook, as I said, is nerdy, but useful. Mystery has covered all the basics and left nothing to chance. If you manage to master Mystery Method and nothing else, you'll still be pretty good. But as I said, try to get the structure, don't get lost in the trees so you don't see the forest. Another good place to start.
I personally don't like Ross Jeffries too much. For starters, his NLP materials are in english, which is not my primary language, so they are not that useful to me. And then, his NLP "tricks" sound like manipulation to me. Maybe it's a limiting belief of mine, I might try using NLP in the future just to see how it goes, but from what I've read it didn't struck a chord with me. However, it seems to work nevertheless, or so they say. I must remark again that I don't think his material is
bad, just that it seems
incongruent with my personality, and that's why I've avoided it. As always, YMMV.
It's very important that you also learn to be a good lover in bed. There are many free websites about sexuality. Try to learn about sex as much as you can. There's is also David Shade's book which seems to be the bible for ASF people, though I find it a little weird with the hypnosis stuff and such, but it has many many valuable tips. My own advice: in bed, be dominant, but focus on her pleasure first. Foreplay rules. Being good in pickup will help you get them, being good in bed will help you keep them.
After picking her up and sexing her, you need to manage the relationship with her. That is, if you want a relationship. I recommend relationships before one-night stands because they are more emotionally fulfilling, and, let's face it, most people who learn pickup actually long for the emotions of having a person that truly loves them. For relationships, I can only recommend one person: Franco. Grab his archive at ASF and read it. Twice. But still, for Franco I'm biased since I consider him a mentor and I personally appreciate him very much. YMMV. But he's the best.
These for the basics. There are more advanced materials but it's best to read a bit, practice a bit, and so on, than to devour tons of material and get a mess in the head. If you try any of those please report back, it will be very insightful for the rest.
