Yesterday I was on a conf call during my son's soccer practice. I was walking around the woods with my daughter at the same time. I was doing none of the above well.
It occurred to me recently that most folks who have been promoted around me don't have children, or just started to have children. There is no upside at work, only in your life.
[edit more] And this morning my daughter told me to get off my phone as I was checking emails (I'm oncall at the moment).
Kids absolutely know that you aren't paying attention to them.
I'd love to quit and just take some time off. I worry that this is the wrong example to set. I've been working regularly for 20 years, but my kids don't know that. But I dunno... thats just fear I suppose.
