I Agree, But Routines in my Opinion, are Needed, well not needed but are a help, as i see it don't rely on them so much, but have them there to have fun with.
And Knowing about Body Language and Seduction and Stuff could help rather then just being Naturally Talking but not understanding what shes putting out, or what you can do to esculate things quicker.
NLP, and body language is IMPORTANT.
Routines can help, I'm between half canned material, and routines, and half natural, I believe that a 'mix' is needed, while I preach no school, as each school of seduction has a lesson to be learned, that can help you become even a better pickup artist. I've studied Natural, and I've done natural, I use Mystery Method, I use some skills from Speed Seduction. Everything I do in field, is a mix. But more importantly, their are some points that are KEY in the field.
And appearing well groomed, and semi-attractive.
Going to the gym helps too. I've been improving every weekend, I'm edge line full pickup artist soon, and I've began to train two new pickup artists to the community in my region to get a lair started, I live in the middle of ass no where. I have to train my wings.
