My pleasure. You were probably overwhelmed by her hotness and you felt like a fish out of water saying what you did because it's new to you. But notice how she didn't scream for you to get away or throw her drink in your face.
It went well. And you'll get better at it the more you do it.
I'm intuitive and I know what I'm talking about
I learn from what I've experienced and what I see. I would suggest you learn about affirmations online. There's tons of free content concerning it online and on Youtube.
Affirmations might take some getting used to but they've helped me and countless others in many different areas of life. Another thing I do is before I go to bed I think of three things I'm thankful for. I think about each intently so I can feel all the good feelings well up inside me. Doing this helps me be appreciative which keeps my mind positive. And positivity breeds confidence and self-improvement.
I think you would be good at banter because of what you said to her. Banter is simply being playful and creating attraction. Offhand, I remember you asked her if you could have her hat. That's banter. I bet no guy has ever said that to her and it's humorous - especially since I'd imagine it's a woman's hat. And she's probably used to men asking for her number, for sex, etc. but not something silly like her hat.
Plus you started with nonsexual banter which is good for newbies. A lot of newbies start with sexual banter and it blows up in their face because they don't know what they're doing. Once you're comfortable with it you can begin using more sexual/open banter (after all - making your intention known with a woman is the right way to go but I've found a guy needs to be in the right frame of mind and have his body language solid before starting an interaction this way).
Inner-game is how you feel inside/your confidence/how you view and treat yourself and expect others to treat you. By improving these things you will improve as a person in all aspects of your life. It's a beautiful thing and when it happens you drop the B.S. from your life and no longer accept it. This includes crappy friends, settling for things and accepting the reality most people accept to name a few....
