Good Little People

I heard something interesting on NPR about a long-term study of parents and children.
Some parents said they hoped their children would be successful, some happy, and a third group just wanted them to be good people.
When the children were interviewed as adults, it looked like the parents got exactly what they hoped for: the successful kids were successful, the happy kids were happy, and the good people kids were good people. But the children whose parents raised them to be good people were also the most likely to consider themselves happy and successful.
