"Pushing" the child for the fear that their potential is not reached. I think that is the dilemma for some parents. How do u define "push" or "encourage" ?

We all know that talent is nothing, without hard work.
I see a difference in those kids who "made it", be it an Olympic gold figure skater or a famous singer. They do not aspire to be "someone" but themselves. There is this inner drive in them that makes them want to do what they are good at.
We, parents, provide the support and the encouragement.
Arts to me, is something to be enjoyed. Yes,daily practise is a must but it shouldn't be a chore when they get started.
To the OP, I think this is something u need to decide for yourself and your child, how much is enough.
