Same for me.
Work is what I do to live. not the other way round.
I work as much as I have to and leave at 4 every day.
But if its an emergency or cannot be avoided then I will work until its done.
I am working every weekend now until Christmas and have planned to do so, but will have the extra effort appreciated. The important part is that it is seen as extra effort.

I cannot see the point of working so much that I never see my family and friends. No amount of money is worth that.

To put this into perspective, my father worked his a$$ off, he was always at work, seven days a week.
After he retired, he survived 5 years before dying (July 04).
No thanks.
