Ennui (noun): A feeling of listlessness and dissatisfaction, often accompanied by an overwhelming sense of pointlessness. It's like a mix of ennui, ennervation, and ennervation-fatigue. Ennui can be caused by, but not limited to: watching paint dry, waiting in line, or listening to elevator music.
In a world where everything is meaningless, why bother trying? Ennui is the ultimate existential cop-out. It's the perfect excuse for not doing anything, because, honestly, what's the point?
Good luck with that. We're not really here to help you, but if you insist on trying, we have some techniques for you. Or not.
