I know this is a cliché as fuck question, but rather than be bitter, depressed, and vent AGAIN on reddit about how I'm almost 21, have never had a GF, and get a strange vibe from women that they want nothing to do with me, I wanna know how to give off GOOD vibes to people. More generally, I want some links and tips on how to exude confidence, be less self-conscious about my height (6'4" lanky) and physical appearance, be more talkative, and approach because I think right now that is the absolute no.1 thing holding me back.
