Most important points are:
- 60 hour+ weeks deliver a brief increase in productivity but you need recovery time right after or productivity plummets.
- When overwork becomes the norm, people think they’re more productive. They aren’t.
- Knowledge workers should only work 35 hours/week.
- One of the main proponents of the 40-hour work week was Kellogg’s. Not out of idealism but because it increased productivity for them.
Or as Psalm 127:2 puts it: It is vain for you to rise up early, to sit up late, to eat the bread of sorrows; for so He gives His beloved sleep.
