When I'm off the clock, I am OFF THE CLOCK. I don't take work home with me, and I make a very diliberate effort not to.
I'm all for Capitolism and hard work, but I don't believe in reincarnation, and I've never heard of anyone on their death-bed saying they should have spent more time at the office.
Employment is a means to an end, not the end itself. For me to bring work home with me, there would be no end, other than my work. That will never happen.
There's about 8 billion worthwhile persuits/hobbies/places/people and things that are well worth checking out and being a part of. If you don't design your life to be a participant in those various things, it's quite easy for the rat-race to consume your entire existance.
You only get one shot at a life, and to let your employer define what that is, in my opinion, is a grave mistake. It's a simple matter of time. We all only have so much (or so little), and how we choose to spend that time, even mentally, is a thought process that is of the utmost importance to me.
The song "Time" by Pink Floyd says it pretty well.
