I have two daughters, both middle teens now. Never push, just gently nudge if needed. Let them make theier own desicions, after you have discussed it with them. Help them with making decisions. Never punish them for anything directly, let them know the reasons instead. Let them know they did wrong by your disapointment, but always through your love in with it. And be their chearleader in everything they do. Always make a point of telling them you love them at least once a day just out of the blue. Hugs go a long way too.
I have watched them excel to national champions several times in diferent but similar disaplines. One is in college now instead of tenth grade. The other I imagine she will still be a straight a student and loved by everyone, she works hard in what she wants to do, she'll get there. I have no doubts about that. Teach your Children well.
