Being yourself means liking what you like and doing what you do and not apologizing or attempting to cater to a woman to garner her interest. It's not about remaining in a losing position and continually getting screwed over by women or being socially inept because 'that's who you are'. It's about being the best you can be and being aware of all ramifications when dealing with women and protecting yourself, all the while avoiding compromising who you really are, and thus developing a fake personality in the process. You can probably get more quantity if you develop a chameleon, morphing personality, but really, you are losing the only thing unique to you in order to slam some hoes.
What are any one of these women really bringing to the table for you to develop a whole new personality? That also sends a powerful message about one's self. You don't deem yourself as worthy and also deem what the woman has as so full of worth that you are willing to discard your own self and create a mirage in order to con her to dealing with you. If you sit around all day making up techniques to pull women, you're going to end up missing that woman that would have liked you for you because you are too busy being somebody else. Sooner or later, you will end up getting tired of doing the theatrics and your natural personality will come through, and the women that were attracted to that image you put up will end up peeling off because you 'turned into a different person'.
