The Work-Life Balance Hoax
How do we know?
Try doing this. Stand next to a wall that is at least as high as you are tall, so that you are upright and looking in a direction parallel to the wall. This will place one of your shoulders, and the outer edge of the foot on the same side, against the wall.
Now try to lift your other foot without falling away from the wall.
Simple physics and many other forms of reasoning will show that you cannot balance the subset against the superset — except in one case.
That case is when both sets are identical, which in this case would mean that either your entire life is work, or your entire work is life. This gives perfect balance.
Otherwise, accept that work is part of your life, and that you will die without it. But do other things with your life, so that you don't die OF work.
And remember: there is no such thing as 'work-life balance'.
