... Being resilient has a lot to do with perspective. “People who commit themselves to a life of learning show up with curiosity,” Mr. Sinek said. “They show up with interest. They show up with a student’s mind-set. You don’t have to be curious about everything. You have to be curious about some things.”

Those who routinely and consciously engage in learning become more confident about their ability to figure things out once a crisis hits, according to Beverly Jones, an executive career coach and author of “Think Like an Entrepreneur, Act Like A CEO.” “Each time they hit a bump, they spend less time lamenting and quickly turn to determining what they must learn in order to climb out of the hole,” she said.

To better understand the experiences of teenagers during this unique time, my colleagues and I fielded a survey of 1,523 U.S. teens from May to July this year, asking about their mental health, family time, sleep, technology use, and views on the race-related protests and the police. We assessed mental well-being using four measures: life satisfaction, happiness, symptoms of depression, and loneliness. We then compared the 2020 teens’ responses with responses to identical questions from a similar survey in 2018.
