I hate being shy around cute girls i know and blow it because im to scared to start a conversation
I always blow it!

Good luck with that maybe start with average looking girls and move up to the ones you think are cute. And remember how lucky they woud be to have you, confidence is sexy!

Maybe try seeing the next few pretty girls you meet as practice runs and don't expect to get anywhere, but see if you can hold a conversation. Practice makes perfect!
