I'm dead serious about it. My biggest hope is that my kids will leave the house, hit the real world and say 'Oh. This isn't nearly as tough as I was expecting.' We had our first at age 21 and she turns 20 in two days. We lived inside the city limits of DC in a neighborhood where the average income was two parents - one a doctor, one a lawyer. My kids knew we were poor in comparison but they learned to value what they had and to earn what they wanted to have.
My folks paid for things relating to education and personal development (ie music lessons and science camp were covered, scuba lessons and gear I had to earn myself). I figured I turned from a punk ass high school to a guy who stood by a girl he got pregnant and scraped to the point where the family is now pretty comfortable. Must have been something worthwhile in their values, so I tried to pass them on.
