You can't do this: I know lee priest, the bodybuilder. He's your height; here's a photo when he was 17. You're not going to be taller. Your muscular development, leanness and athleticism are entirely under your control. A shorter man can be wiser and funnier without frightening others and may be preferred as a friend by other guys. Embrace who you are and build up what you can. You simply can't fret about this.
