Feeling weak!

Maybe physical fitness really does matter. Feel that I'm moving kinda slow while balling and can't hold the ball well... I'm causing way too much turnovers!!! Arghh.. Another reason is maybe I'm too chilled. Hahaha, don't seems to feel exhausted after games, maybe its because I don't have the chance to be tired or because I'm too relaxed and doesn't move much... Aiya, whatever man, I just got to do something about it...
