Do not pollute your mind. Think about this, you are talking to a arrogant women and you believe that she is of lesser or equal status to yourself so you believe that you can talk to her with no problems because the outcome does not matter to you. You are not seeking a reaction in the woman.
Suddenly when you are talking to a "nice solid lady" you are looking for her to show you that she likes you, you are putting on a "shtick" or a "song and dance" to impress her and your going into your head to fish for ideas on how to impress her.
This is what you are thinking when you do not want to neg her, you are going into your head and saying to yourself "i dont want her to feel negitive emotions towards me so i will not be myself I will be what SHE wants me to be"
How do you know how SHE will want you to be? You don't even know her. She could be a "nice solid lady" that loves sex and is comfortable enough with herself to laugh off that neg and maybe shoot one back at you playfully.
Just by writing "I would like to date this girl" is putting so much emotional pressure on yourself to "PERFORM". CUT THAT OUT, do not perform for her or you will loose her. Be a man and take the conversation in the direction that you want it to go. She wants you to lead, if you are bored of talking about weekend plans, childhood dreams and the weather then whatever comes to your mind ask her.
"Amuse yourself and you will amuse others" If you whole heartedly believe that what you are saying is interesting then she will feel the same passion that you are feeling. Humans are mirrors, if you look in her eyes and speak about whatever you want there is an outpoor of energy and you are infecting her with your positive emotions
BE AUTHENTIC. Authentic communication is what everyone on this earth responds too.I could go on and on but my fingers are getting tired
Anticipate positivity, do not depend on the outcome
