Boredom
Boredom is friction.
If I could change anything...
I would change people's motivation.
Boredom cannot magically disappear.
But magic motivation makes boredom melt.
Boredom indirectly encourages the seeking of novelty.
If I could make motivation appear, then boredom will depart.
Bring forth buckets of motivation for us and all and boredom'll die.
