I've been reading the pick-up-artist forums for 3 years now, and the main issues that i saw from both the beginning and now are
inner-game. A friend introduced me to a 4 season series called Spartacus and hell, i have to admit, it has helped me strenghten up my inner-game by a lot. Basically, it's about a roman called Spartacus, a Thracien who makes an alliance with Rome to fight against a tribe that attacks their village. Rome screws Spartacus over and Spartacus gets him back. With a cost, he is stripped from his wife and sold as a gladiator to a gladiatorschool where he undergoes the toughest training and most harsh enviroment. The rest is up to you. Despite it being a series, it is still based on the legend of Spartacus himself, ofcourse not all the details that are included.
The reason why these series have helped me is because of the personalities that these men reflect. Every single one of them went through gigantic losses but passion keeps them driven. Same as getting rejected from the field, but still carrying one for a greater cause in our life.. Improving it. These men become the definition of alpha and from trembling fear, they are forged into men that dont fear loss. All by working hard, practice and failure. At the end, they dont fear death, they embrace it. Same as we'd embrace rejection, or relationship break-ups.
It's not about the tight masculair bodies, they all started with nothing, just like us. it's about their mindset and the goals they want to archieve, Spartacus is a great serie to show you heads on how far ambition and passion can bring you, both in and outside the fields.
There are a lot more aspects aswell. Dealing with the AMOG, how they talk to women, shit-tests, dialogue (The best part imo) ... When you've read some PUA books, and watch these series, you'll often say - Fuck man, that was fucking godlike!
Anyway, i highly recommend these series, they
WILL teach you a lot.
Awesome quote i run by - A man must accept his faith, or be destroyed by it.
Trailer - will get you warmed up.

Things I learnt so far:
1) Wording & a powerful way of bringing your message.
2) Definition of alpha.
3) You have 2 ways of living, you either end up chasing someone's dream, or end up chasing yours. The choice is for you to decide.
4) Being the AMOG without being an arse to your surroundings.
5) Live for yourself, not for others. Society has us bound, parents want us secured, we follow other rules, not ours. Take a turn, and start your own wishes and desires.
6) Passion, how to reflect it, what it does with a person.
7) Beliefs/opinions & the importance.

How to deal with rejections and become stronger.
9) How to deal with shit-tests.
10) Does a body or a face really decide for those HB10's to fuck with us or not? No, it's what's inside your head that does.
There's probably a lot more.
