This feels a bit short-sighted to me. Maybe it's just use of terms at the end of the day. Telling a young person to "lean into boredom" is a recipe for disaster. And "thinking" as the antidote to boredom doesn't do much either. There's a quote that always stuck with me I ran into a while back that goes something like: "All day long we tell our children to 'Pay attention!' but we never actually teach them how." The premise of this article, IMO, would be much more valuable if it dovetailed into meditation practices.

It's always been my take that one of the main reasons many of us seek out typically unproductive distractions and noise (phones, TV, gossip, whatever) is to avoid quiet, personal, thinking. In jail, which is presumably the worst environment one could find themselves in, solitary confinement is viewed as a significant punishment for bad behavior. Being alone with your thoughts is worse than being around criminals all day or locked in a cell! I think "lean into your boredom/thoughts" is an empty provocation without training advice (again, meditation is the route I'd take this).

“All of humanity's problems stem from man's inability to sit quietly in a room alone.”
