We miss a lot of time from our families. But we are showing our kids the reality of the world, that what they see on TV isn't how the world works. We work long hours, but our spouses are freed up to work PT, or not at all if they choose. Our kids learn to get something, you often have to give up something else. My kids and wife have always hated my hours, but they understand what benefits we derive from this. My kids stay out of trouble, make good grades, and are well regarded by the people around us.
I go to all of the events they participate in that I am able to, so they know I'm not ditching them when I'm not there.
It's not easy, or fun to be gone all those hours,but if we give our families quality time then the quantity isn't as important.
