Ah, I may have misunderstood your comment. I thought you were leaning more towards the "dream" part. But so my comment also meant to say that the definition of ambition and success changed after becoming a parent. I know I won't be curing cancer in my lifetime and so what thing is really important that I have to sacrifice time with my children for? To me, being the founder of the next failed facebook for cats is just not it.

Note that I am not talking about earning a living and thus necessarily sacrificing time doing that and showing your kids that sometimes you have to work hard to survive in a decent way. I am talking about the parents who outsource their children to childcare to work to pay off the loan on their third car and newest iphone and tell you that they have no choice.
