Sometimes I am already paralysed by fear when thoughts about my future take a dark turn (relatively often), but at the end of the day it is my well-being (and my wife's) we are talking about, and we are economically independent adults. We could take a hit or two.

With kids you will worry as much, but over different things. And also the old things, when you get time over to mull over those...
I don't think I'm capable of putting into words what it feels like when the doctor hands you that baby. But I can say that I don't care as much what kind of vehicle I drive, or what clothes I'm wearing, and it seems silly how much thought I used to put into such things.
But I do see enough parents who obviously see their kids as nothing but an anchor to know that it's not for everyone. Some people aren't ready, or incapable, of shifting the focus away from themselves.
