Yep, biccy... you will end up the height you are meant to be... you can do extra exercise to develop those pecs etc but to be honest, most girls go for a guy's mind and attitude, not what physical size he is. When I was at school (errr, far too many years ago) the most popular person was actually not that good looking or attractive, but she had the most beautiful smile and always made everyone feel really good about themselves.... When I went to Uni, once again the really nice people were the ones you wanted to actually spend some time with cos they made you feel nice about yourself. So, the moral of the tale is, be yourself, be honest and fair and treat others as you would like to be treated... you will soon find that you have a load of lovely mates (both boys and girls). Physical growth won't really matter to any of you in a few years time.
