I had to wait too. . .Three years. Play paintball in the meantime and work on being a tactical player rather than a 'speed-ball spray and pray' player. You can win entire games in airsoft without fireing a single shot.
Be patient, Ask questions, Do your homework and reasearch. when you're old enough it'll all be open to you.
There's even the unlikely chance you may not even like this game. I have firends that would rather play paintball becasue 'airsoft is too slow'. I think they're crazy.
