I believe that having/possessing the correct/adaptable/conducive mindset/thoughts when you interact with girls immensely help you get a girl, sometimes I can even say that as long as your mindset/thoughts are correct, your words, your vocal tonality, your body language can be guaranteed to be correct/proper. The mindset/thoughts contain how you view yourself, how you view the girl, how you view the interaction. In my understanding, I think that the conducive/correct mindset/thoughts should be:

About myself: I'm a desirable man. Life is great. I'm lighthearted and playful.
About her: Her appearance doesn't mean anything, if she is lighthearted and playful as me, she is desirable.
About the interaction: I'm offering her a chance to get to know a desirable man, and I want to see if she realizes it, if she doesn't realize it, that's just her loss.

Or maybe we should have different mindsets/thoughts when we are in different phases.
Below is my version:

A0(Motivation): I am not a playboy, I'm not wasting my life. I want to find a satisfying life partner now I'm working on it. I take the initiate to talk to girls so I can get to know girls and screen them one by one until I finally find one who can become my wife. I know that some girls will respond to my initiative icily/coldly, they may even give me an annoyed look, but I don't care. As long as I want to find that satisfying life partner, I know that I have to bear through the discomfort again and again. But it won't kill me, the discomfort won't actually bother me much as long as I don't ruminate it. A girl I approached may not think highly of me, but I don't look down upon myself, because I know that I am a man who is responsible for my life, and I'm earnestly living my life.

A1(Open): I'm a desirable man, no matter if a girl actually desires me or not. I'm going to find if she will' find that I'm a desirable man.
A2(Female-to-male interest):I respect her as a person, but I am not interested in her. I'm playful and lighthearted, I also would like to let her find that I have some other high values.

A3(Male-to-female interest): (Before you find her good points), I'd like to encourage her to say something about herself, so I can know something about her: (After you find her good points) She is not as shallow as I thought at the beginning, or just another girl among the sea of people, she has some interesting points, I'm a little surprised.

Comfort: I feel that there is some chemistry between us. I want to know more about her, I feel that I can trust her more, I can say more about me to her, I also want her to know me more. I naturally want to touch her, to show my affection towards her.

Seduction: I want to further connect with her. I want her to experience the pleasure of sex.

What's your idea?

That's some great stuff and it's pretty much exactly the same as I see it. Your beliefs are the source of all your behavior and your behavior is what does or doesn't generate attraction and connection.

Below is another version:
A1: I want to talk to this girl, this group of people or this guy to develop my interpersonal skills, the skills of relating to people.
A2: I am not interested in the girl, but I like to talk to the girl(or the group) to develop my interpersonal skills, I want to “unintentionally” leak some of my high values and see if they can notice them and how they will respond to them. I respect them, but I am not seeking rapport, I’m not trying to please them. On the contrary, I will mention some negative points about the target during the conversation at proper time and see how she will respond.
A3: The girl/target becomes interested in me, I like an attractive and decent girl who is interested in me, I want to know more about her, I need to encourage her to talk more about her and see what points in her I am fond of.

C: I want to know more about her, and In the meantime I want to let her know more about me. I start to naturally touch her because I think that we have become “friends”.
S: I sexually desire her. I also want her to enjoy the pleasure of sex(with me).

Please advise.
