I'm assuming that you don't have much experience with girls so my advice is for you is to interact with as many girls as possible while being confident even if you don't feel that way on the inside. The more you interact with girls the more you know about what they like and don't like. An example is that I always thought that girls like to have deep conversations but every time I had one with a girl she would get bored quick so I logically I tried to keep a light and humourous conversation and it worked magically. And don't forget to take care of your looks, like getting a haircut, dressing nice, and taking a shower daily. In short if you want to know how to play the ge right you have to observe what females generally respond positively to, this can be from your own experience or by what you see other people do.
