I'm really good in gym because I play tons of sports, but my friend Emily isn't so good, but she finally found out that she's really good at swimming! So if you find a sport that you really like, just keep working on that PARTICULAR sport until you get really good at it. And if people start getting mad at you because you don't play that well in the sports during gym, don't get down, just say that the sport your playing isn't your best, and remember, if you practice and get really good at one sport, (but the people who play a lot of sports are okay at every sport) just think to yourself, even though you don't play a lot of sports like them, your REALLY good at one sport so you could TOTALLY beat them at that particular sport!
