It seems to me that goal of a parent should be to foster happy kids who know how to work. Work without happiness is no life, and happiness without work soon becomes unhappiness.
And I would further say that there are three basic ways of framing “the world”:
1) the world is rough and if a man’s (or woman’s) gonna make it, they gotta be tough. (those might make good lyrics to a song).
2) The world is rough for some people, but you will be taken care of.
3) The world needs to change to suit your needs. Any pain or difficulty anywhere is cause for outrage.
Expectations set moods, and moods set lives.
