SOCCER?..I CAN'T PLAY SOCCER!..WHAT TO DO?

*SIGH*,i has experienced this kind of situation..i really can't play soccer/football..here is some interesting story i had..few years ago,i join the rugby team in my school because of 2 reasons.
              >to get girls attention(hu huh,i know what you think..:D)
              >because i can't play soccer/football.
when i said i can't play football,it's mean that i dunno why when the ball is put in front of me like when you get penalty kick,and when i kick it,i only kick the air and fall without anyone touching me(because of the force from my kick that make my fall)..During my time with the rugby team,i was chosen to be the team captain because i can do well in drop kick..(i kick very far) but when the couch  ask me to kick it like normal,not drop kick..the same situation with soccer happen..but this time the ball only roll over(maybe because of the ball shape)..argghhhh..anyone out there can help me with this?..
