I only have a 45min commute and I still only get to spend around 1 to 2 hours with my kids during the week. Some days I'm too tired to even make best use of my time with them. I'm currently looking for a new job in London which will put my commute just shy of "extreme commuting" knowing I might not see much - if any - of my kids during the week. But I can live with that because of the opportunities it creates for our family and the most valuable time I spend with them is the days I don't work anyway.
