If I were you I would record myself talking to women. Listen to your voice to see if you are up talking which is something people do when they are nervous like giving a speech on class. Be sure to down talk it sounds more dominant and women respond to it better. Also be sure to make the girl laugh and find a common interest with her. Be sure to be polarizing which is talking about what you want and not giving a fuck. Like I said I would highly reccomend searching simple pickup on YouTube it will change your life. Talking with girls is supposed to be FUN. You shouldn't feel like it's the end of the world if you get rejected or if a guy to walks past and you don't say anything at all.
