Being fit is about the only confidence booster I have going for me right now. Usually shorter guys can get ripped easier than taller guys so try to become an animal in the gym. Get a pre workout and go fuck some shit up. Have you ever thought about volunteering? I've been thinking about volunteering at an animal shelter because I feel great when I do something kind or unselfish. I'm sure it can't be a bad way to meet girls, either.
