Yes, there is a range of what most of us consider acceptable for the hours we will put into a job and this can also change accordingly to what's going on in our lives.
Achieving work-life balance is easier if you start with a vision of what your ideal workday and evening would be. You can also create an ideal non-work weekend day and evening. Just as goal setting for work helps you to work to achieve those goals, goal setting about your ideal work or non-work day and evening will help you to achieve that ideal schedule.
Once you create your ideal schedule, you can at least see how close to that dream your current situation is or what you can aspire to at this job or in the future.
