If you have kids, stop doing this to them. You're their father/mother. Love, nurture, train, and instruct them to be good people. If they go to Harvard, good for them. If not, Harvard be damned, they're your kids.
If you don't have kids yet, mature before you do.
On the other hand, my son aspires to become a lazy couch potato and gamer. He's actually quite successful on that front, but I admit I was hoping for something more.
However, we have not all ended up in the same place. One of my brothers managed to spend over half a decade in and out of odd jobs, spending all his money on drugs (thank fuck none of the hard stuff). Me and my other brother have managed to carve out a good life for ourselves, at least by society's external measure.
People will go their own direction in life. You can prod them and help them on their journey, but you can't fundamentally change who they are.
