If something doesn't come natural to you, then you have put extra effort into doing it. Some people are naturally outgoing and are great conversationalists, others suck at it. But what all humans are capable of doing is being an actor. We put on for others all the time, whether it's to sell a lie or manipulate them into doing what we want. Pick up, for all means and purposes, is just an act. We are actors who play the role of womanizers and gigolos. Mating rituals in the animal kingdom are just an elaborate act as well. Often times they are a performance which invovles dancing, singing, and displaying flashy colors. In pick up we call that peacocking, attraction, and seduction.

Routines have been developed to give pua's a "script" which they can use in their "act" when they open sets. They actually suggest taking improv classes and public speaking to help you improve your skills. I think taking acting classes would be good as well, but being a real actor is much harder. Your "frame" or "lens" is just your character's motivation. You just want to be you at all times, but you have to be someone else in order to get laid. That's why you need to learn how to put on this act in order to attract and seduce women and be perceived as a socially proof individual. Ideally, at some point down the road this will all become intuitive and instinctual and the character you are portraying will begin to integrate itself into your own personality and will become completely natural.
