I'm not sure what to do about Ballet...can you help me?

I took ballet when I was 7 and 8, then I quit, I'm pretty sure that I want to start it up again, but by the time I can drive and take myself I will be 16 and too old to develop good skills and muscles. Should I start training myself at home? I would aks my mother or father if they would take me and I could pay for it, but I already take piano,cello, and all of my cles...what am I to do?
