We tend to think of the five-day workweek as a law of nature, as certain as the rising of the sun. But it's nothing of the sort. The five-day workweek is a human invention that was introduced just over a century ago to solve the specific problems of the industrial age. By now it's so ingrained in our lives that we've forgotten we created it in the first place-but we did create it and we can also un-create it.
What's the big idea? Why do we fall into the same patterns-whether that's people-pleasing, perfectionism, or emotional numbing-even when we know they're not good for us? These strategies help us feel safe, but replacing that armor with inner strength lets us move with freedom instead of fear. Listen to the audio version of this Book Bite-read by Kati herself-in the Next Big Idea App. 1. Control is a survival strategy.
The Yerkes-Dodson Law, first described in 1908, suggests that our performance improves with physiological or mental arousal-but only up to a point. Picture a bell curve: Too little arousal ( boredom, fatigue), and we underperform. Too much arousal ( anxiety, panic), and performance drops. Somewhere in the middle is our "zone of optimal arousal," where we're alert, focused, and effective (Yerkes & Dodson, 1908).
