Bull****. The world is littered with rich men who settle for scraps. If you're not getting anxiety then you're not pushing your comfort limits enough, simple as that. Ever gone for a hot daughter's number, cold approach in the street when the mother was right there, and had them both into it? I have, and yes, it made me nervous. Anyone can milk social circle game without anxiety, been there, done that too. Not everyone can build the social circle. If you can, good for you, but tooting your own horn and putting down others who are trying to learn a concrete, functional methodology to actually get there does nothing but stroke your own ego.
You're just another guy who passes by the 9 on the street without approaching her because *gasp* spitting a canned line is too "loserish", then you soak up the 6s at your friend's party later on in the weekend. Nothing wrong with that, other than your incredibly pretentious attitude about it towards everyone with potentially less fortuitous employment, genetics, or location. I guarantee you that I've been in easily 1000x more potentially life-threatening situations than you have, and have the scars to prove it, so spare me your "fires of life" ego stroke. Sober cold approach takes balls.
SF and even NYC is full of guys who make a ****load more money than you do, dominate their industries, and "live their (non-sexual) dreams"...but still can't get laid by anything over a 5 on the reg, and settle for a gold-digging 7. Say nothing of every small town between the two cities. In the geographical majority of the country it's simply not a realistic goal to sleep with lots of attractive women from social circle, at least after college.
I'm in the top quintile for income, have no trouble getting laid if I want to when I'm in a new city, which is every few weeks, and yes, I still get approach anxiety. No shame in that. I push through it and make it happen. I know plenty of guys who make more money than I do, and probably you as well, but can't pick up girls to save their life, because they let the anxiety dominate them and never learned a framework to build off - which PUA offers. It's not about running around in a velvet cap with pilot goggles on anymore, get with the program. Every piece of actionable advice here can be traced back to the game pioneers.
