I completely agree with this writeup, but I believe it depends on the child. Some people feed off of the energy and creativity of outside influences. As an introvert, however, I get overwhelmed over time of being unable to quiet my mind. There are times when listening to my radio will make me feel I'll, and I'll shut it off for weeks as a result, until a time comes along when I want to drown out the chaos rolling around up there. Also, having someone constantly talk to me to try and help me stay awake on a road trip actually has the effect of putting me to sleep, because my brain starts to idle when it's being fed constant stimulation. Imagine explaining that to a loved one who thinks they're helping you out. Definitely an arduous learning experience for all parties involved.

I now spend my 6+ hour road trips in complete silence (radio turned off and everyone else asleep), and it's infinitely helpful time to reconnect with myself and my ideas and aspirations.

When I got bored as a kid or young adult, I'd do things like: learn orgami, draw something, learn a programming language, start and commit to a workout plan, create something interesting. Now my life doesn't really allow time for boredom. That's why I needed to get into grad school: to force myself to set aside time to learn and create. I would love a stimuli drought right about now.
