Using routines is okay to begin with, to overcome AA, to become comfortable approaching women, to adapt etc etc and as you get involved more and more, I believe, it is a natural progression that you will eventually stop using them and either be natural, finding enough true stories about you to share with these women, finding situational stuffs to talk about (e.g. so what you drinking, etc) or going direct.
I also believe that every individual has enough interesting stories about himself to share with and hence, build attraction, with his target. If not, I suggest, every
PUA should always strive to build memories rather spend endless hours reading
PUA materials, chasing women....! My point is BE AN INTERESTING PERSON......
