I'm pretty should I would have read the whole thing, probably more than once. I don't think I've ever read the whole thing straight through. When I first came here I read a huge amount. Maybe a few months later I read so more or re-read some things. Perhaps a year later I would come back and go over it again etc etc. So I've kept going back to it over a long time. I haven't read much from there in a long time.
The only things people really need are The Book Of Pook and Weapons Of Mass Seduction. If you ask people from the real seduction community (not what I consider so suave, we are a little bit apart from that) where guys have seen loads of products from 'gurus' and regularly do cold approaches, a lot of them highly recommend the Book Of Pook.
Over the course of years the DJ Bible has completely changed my beliefs. Some of my core and solid beliefs come from there. I don't think anyone needs to read that much. Pimping 101 or whatever the compilation by KillPetaHogg is a great shortened version.
Personally I find that the DJ Bible is just as good if not better than most products you have to pay for. There's a heavy emphasis on self-development that doesn't seem to be found in the mainstream PUA community. Although I did still pick up some limiting beliefs from it I think that by following your own experiences and not taking any articles too literally you can avoid that. Even more important then that is actually going out and getting experience rather than just reading. That's where I actually like the concept of cold approaches, which not as many people seem to be doing here these days.
I don't need to read it any more. Although I might not know every post off by heart all of the fundamental beliefs are well and truly in me. That being said it can be a good refresher now and again. If someone is just starting out I would recommend 100% that they read it. I think the best strategy would be to completely binge on the information for a short amount of time, after that just focusing on one area and occasionally reading an article on that subject. This should be coupled with going out and getting real experience otherwise it's pointless. From then on if people really want to get it down they should come back and re-read the material every now and then, but again there is no point if you aren't using it in real life.
Hope that helps. I'm always surprised when there's people here who know what they are talking about but haven't even read the DJ Bible. Can I ask how you learnt everything?
Really the DJ Bible is the only thing you need but it needs to be put together with improving yourself in a variety of areas, improving your actual life, getting real life experience with women and working with you inner game. Some of these things you may find better information in a different place, but I don't see the need to pay for anything.
