i think my problem is i envision the interaction in my head trying to go over a play by play and imagining what i'd say, what she'd say, thinking of a response and it going south from there. how do i get out of that mindstate where im only thinking about the end goal but also not be "creepy"

do you go up to girls and start dancing behind them and just get rejected and move on to another one? how do you go about it correctly

i picture myself going up to a girl who might be alone and telling her i thought she was pretty and my name...
