I later learned that the quality I was observing was a form of grit: The ability to keep going, no matter what, in the name of achievement. But we had not understood how to apply it properly.
Should we encourage our children to work hard? Absolutely. But young people need to learn that grit is only effective when coupled with restorative activities like sufficient sleep, exercise, a well-balanced diet, meditation, walks in nature, and time off. Research shows that these basic yet essential self-care habits result in greater focus and productivity, not to mention increased creativity, better decision-making, and stronger emotional intelligence.
