Replying to 18 years old... too old ?

Hi everybody,

i want to ask something maybe a lil stupid but it is important for me.
i am 18 years old, and i really want to learn freestyle skiing.. actually i ski since i am very young but i have never tried to do some tricks. I just do maybe some 180, but that's all...
my question is : isn't it too late to learn? i mean i want to be able to do easily tricks like switch 540 and switch 720 with grabs.. when i see all these guys who are 14, 15, and who already do cork 10 i am just exasperated..

thx !
