I recommend the book Burnout Society

The author makes a case that we are living in an achievement society where the individual becomes both master and slave in the endless pursuit of doing more. We have eliminated the thoughtful solitude of boredom. We have become obsessed with doing and no longer know how to not-do for fear of falling behind.

A good insight from the book raises the point that in the Christian mythology god makes the day of rest the holiest of days.
