This is absolutely true, but the problem is that we are oversaturated with time-wasters that prevent that kind of deep, creativity-breeding boredom. There's always another phone game, another show, more social media -- and these things were specially designed to hold your attention and prevent you from being "good bored". South Park nailed it with their discussion about how the problem with doing pot as a kid is that it makes you OK with being bored. Well, now we have millions of things like that.

Road trips. I remember those wonderful long boring trips before our girls had phones.

Oh, and even after, gee, sorry, not charging phones when on the road.
