Rhythmic gymnastics? - rhythmic gymnastics

I intend to start soon in rhythmic gymnastics. I'm 16 and I'm kind of flexibility, I have figure skating for a few years, but are levied by no means the stage at which Turner.
I want to know how long it takes for someone my age and the ability to be good in sports? Of course I did not dream of going into big competitions, but I like most things I do well. Should I train a lot?
Thank you.
