Again, I have no first hand experience (other than being a high school student three decades ago)...
However, my step daughter just started college... super great kid... never in trouble of any kind... always got A's and B's and very involved it sports (soccer/lacrosse/cross country)... her mom wanted to be involved but daughter would have none of it... home from school>lock herself in room to crank out homework>then run out of the house for sports and/or social stuff with her girlfriends.
Just sayin... don't think there is a one size fits all when it comes to raising kids.
At least that is what the voices inside my head are telling me.
