It's important for me to have a good work-life balance. I want to balance my family time with my career.
True.  Working too hard can be stressful and lead to health problems.
Agreed. The term "work-life balance" was first used in the United States in 1986.
Although I wonder how much impact any individual can have over work-life balance.  It's not like people decide their own hours in your average job.
That's a good point. According to a 2010 National Health Interview Survey, 16% of U.S. workers reported difficulty balancing work and family.
