I've been reading the Real Social Dynamics blog for a while, after I saw a post on this forum, and the information there have really improved my social relations. And it's no ego based learning. It's no faking, it's about being the best you. Many of the ideas and principles are spiritual and, as you said, Steve Pavlina-esque in nature. I really like the idea about being in your own reality.
Recently I saw the RSD Foundations DVD and it's worth it's weight in gold. As far as I've heard the Blueprint Decoded is the RSD masterpiece so I can only imagine how thats like :P
Real Social Dynamics is highly recommended
Definitely the best stuff about social relations I've come across so far.
