well, for starters, go to a bar. clubs are more difficult due to the noise.
second, peacocking needs to be bigger and brighter. Big pink cowboy hat is good, bright t-shirt etc. this will help solve your dieing convo problems
Third, write a script. the best way not too get shot down is to write a simple couple of routines down with some scripted speech etc. it avoids the awquard AFC silences.
God i hated those
Fourth, Learn how to cold read and finish Styles book. also purchase "masic Bullets" By savoy, it has more up to date techniques
Fifth, enjoy what they enjoy, "its not lieing its flirting"
Finally, AND MOST IMPORTANTLY.
Your gunna have to learn: THERE IS ALWAYS ANOTHER GIRL WHO IS UP TO FUCK YOU, THEY JUST DONT NO IT YET!
Once you understand this for yourself, you wont care anymore and wont worry about every single girl giving you confidence. They will pick up on this and it will be easier Because you dont care. Not caring even can be a subtle neg.
First is always the hardest, it will get easier.
Good Luck
