Although I appreciate your effort and see that there is a lot of good stuff out there, I would like to make a comment on why it is so difficult to get a synergy. There are about as many methods as there are PUAs and they all work more or less. There are no universal truths really. We all have different personalities and our game methods are simply ways to compensate for or practice them.
Also synergy is difficult to accomplish, as seen in attack of the clones. Padme explains is to Anakin, the problem is that people does not always agree.
Yes, there is a lot of BS out there but spending some time on the forum you will learn who to trust and who not to trust. What you are trying to do in this thread already exists, in the form of a forum. This forum. The difference is that you have selected people that you trust to write in it.
It is not a bad idea but limiting yourself may make you miss stuff you havent thought about, variety is a great thing.
Maybe we should try to write a PU book together.
Anyways, the most important things to get better at game are these:
(In my humble opinion)
Dont fear pain or humiliation, anything is better than waking up tomorrow and be as lousy as you are today.
Learn from everything, a success, a failure, a dog, a cup of noodles, every situation.
Fight your inner demons, eventually they will die.
Listen to others, you can learn a lot.
Calibrate your game and be ready to change directions completely if your plan isnt working.
Improvise.
Dont be a dick but dont be a pussy.
Dont overthink how an alphamale behaves, focus on becoming an alpha male for real and it will come to you.
Dont ever do anything because you expect something in return. A girl is not an investment, she is a person.
Accept that you arent perfect, but dont accept to not improve.
Apologize if you did something bad but never for who you are.
