Let me add...A physical entrapment requires help and strength outside oneself, and the other requires strength from within oneself.
Before It's Too Late ...
If you were in the org for a minute you saw this scenerio play out again and again. Journey-on, we too left for the sake of our children, they were a bit older than yours. We appreciate regular life so much more now, just sitting at a sporting event with the kids or helping the older ones look at college and career choices. I have friends "still in" lament that they wish they could just leave, then do it! It is never going to be easy, nothing worth doing ever is.
