Completely changing my life, advice would be helpful
I am a 20 year old guy and never had a gf before and never even dated before. I have come to a conclusion that my physical appearance and quietness are the main reasons. The only place I could really meet people is at school and I have a hard time talking to people. I do try and get involved with class discussions but besides that no one really tries to talk to me and when I try to talk to people it ends up going nowhere. I do go to a lot of parties but the only girls who dance with me are the female friends I go with all the other girls for the most part they refuse to dance with me. Most of my guy friends don't get rejected so I am assuming that my physical appearance must not be too appealing.
I have decided to turn things around. I am very skinny so for the past 2 weeks I have been going to the gym a lot and changed up my diet. I am really enjoying this and have high motivation. I am no longer going to go out on weekend nights because it messes up my sleeping hours and I no longer have fun at parties due to never getting a chance to dance.
So my questions are, what I can do to make more friends at school without having to join clubs or anything like that? Also where can I go besides school where I can meet new people?
