If a girl can call you out as a pick up artist just because she has read the game or watched a movie, you need to make some changes! If you are just starting out, that's fine because you are just practicing anyway. If you've been in the game for a while, you need to evolve as a person and not just learn the latest routines.
I used to be worried about letting people find out about David Deangelo (which was the material I had at the time) in case they learnt game and there was more competition. I was literally just the sum total of the notes on my crib sheet, if someone else had that, they had my game! Now that I've CHANGED as a person, and grown, no one can clone that or copy me...at least not easily
A good exercise for anyone who is still in either of these situations is to:
Take a good look at yourself. Write a list of all the reasons why a woman wouldn't find you incredibly attractive. Make an action plan for each one.
My original list looked something like this:
-ugly
-not funny
-boring
-no friends
-don't know what to say
-not sexually experienced
-not sexually confident
-bad fashion
-shy and introverted
for each one I made one or maybe multiple action points to tackle them. Took a while but I got there and none of them are true of me anymore. Slightly off topic here (and maybe more inner game) but anyone I think who is worried about their openers having the power taken away or hoards of new guys using lines from a movie on women should take note.
