IMO, if I'm thinking about work more than 8hrs/day, I'm doing it wrong. That's just me though. I love my job, and I love not worrying about it when I leave.

Different employers can have pretty different expectations about this. I always try to let potential employers know it's important to me when looking for a job. Usually it's as simple as "Work life balance is important to me. Can you describe how your company handles that?"

Sounds very sensible. I plan to make it a point of emphasis during my next job search.

same feelings here. All my time is sucked either into the full time job ( writing code, debugging, profiling... and then meeting with stakeholders, debating requirements... and then coaching the younglings management hires oh-so-often... and then, repeat. ) or into the commuting from home to work. I get to the weekends ( when it's not just extra time to finish even more work ) exhausted, praying for a quick and merciful death. Every week. {ironic}The mrs. just loves that routine...{/ironic}

Hah, I feel your pain. I suspect we are indeed "doing it wrong". Best of luck to you!
