I wonder though, how much of it is just an extension of what the parents want for the child. Like if the child shows excellent talent for a sport, and the parents really push it, taking them to the best coaches and all the rest, only for the child to then say they want to stop doing it after a few years - how crushed would the parents be? Would they be devastated or would they be able to just say "ok, I'm cool with that" after all the time, effort and most importantly money, they have invested in this child.
