In automotive, working at a manufacturing facility, it comes with the territory. 70-80 hours for many years. I also traveled out here alot, sometimes 2-3 times a month. Even did a 3 year stint setting up a plant in the Netherlands.
Even though I lived in a really great area, I was at work or traveling 95% of the time and couldn't enjoy the lifestyle that I wanted. No time to boat, hike, or ski. SO, I moved out here instead and now pretty much have a 40 hour week every week.
I gotta tell ya, I'd trade all the $$ and success I've made for that 70-80 hour job to be able to move back to NH...
...If not for the kewl people I've met during my time in ichigan, I'd a done it along time ago...
