My ex-Boss at Walmart Strategy had taught me good wisdom of balancing work and life. A good way to think about this is picturing two vases labeled "work" and "life," each filled with water. Then acknowledge you don't have to spend them all in equal amounts. No one will force you to work exactly 40, 50 hours per week. There is no need even to keep track of it. When you are free from this no-need pressure, you become much more fluid about how you think of managing both work and life.
