Ride the bus once without a screen. The window has been trying to give you ideas for years.
STILLNESS
STILLNESS
A window gives your attention something to do that demands nothing back. Watching a place go past is one of the few kinds of input that leaves room for your own thoughts, which is why ideas turn up on journeys. A screen fills exactly the space that would otherwise do that work.
Take one trip this week without reaching for anything. Watch what goes by and let your mind go where it goes. It will feel like twenty wasted minutes right up until the moment something useful surfaces.
What might you notice on the ride without a screen?
Free, with nothing to buy inside it.
