For you

If you can sit with boredom long enough to think, read, practice, or make something hard, you are building a rarer skill than it feels like.

What would change our mind

This call weakens if the next Common Sense census shows teen entertainment screen time falling below seven hours a day and staying there after school, sports, and in-person activity normalize.

Behind the numbersOpen

Common Sense Media’s census measures entertainment screen media use among U.S. teens ages 13 to 18 and excludes time spent on school or homework. The observed values are 6:40 in 2015, 7:22 in 2019, and 8:39 in 2021. Decimal values convert minutes into hours: 6:40 = 6.67, 7:22 = 7.37, 8:39 = 8.65. The 2021 jump includes the pandemic period, so the main caveat is that some increase may reflect temporary disruption, not only a permanent patience shift.
