Wow, there are a lot of really interesting thoughts and beliefs out there regarding this PUA stuff.
Let me throw my hat into this ring.
PUA stuff does work, is it a tool for overcoming serious anxiety... probably not.
The stuff out there can be good, David DeAngelo's stuff is actually the worst but he is the best marketer out there, if you check his listing at alexa.com he beats any of the other guys hands down at present.
What this comes down to is will a quick fix, i.e. learning stock material and things to say help you over the long term, or is it just going to mask the problem? In may end up doing both, as you gradually become more confident over time...
This will vary depending on what your current challenges are. What I can say is that I used that stuff very successfully to get over any anxiety I have in a night time social setting consistently.
It didn't happen over night but by going out and pushing myself (I refused to take meds) I got comfortable and now have a lot of close friends and people in my life.
I still have huge anxiety just going shopping or jogging and I'm now applying the same formula of gradual exposure to get over these things.
So what I will tell you is that:
1) Not all this stuff is a scam but David D def is
2) It's not a guaranteed fix but it can definitely help
Additional: My boss is 36 and he dates a 21 year old, I have a friend who is 46 and dates a 26 year old, if you want to date a younger girl that can happen but it's easier to say "I'm over the hill, I can't get those kinds of women."
What you decide is true will be true, but if you are willing to let go of that belief then I urge you guys, next time you do make it out to a public setting look around, I saw 4 older guys with younger women today. And no, the guys didn't look rich or handsome.
