Why “hyperthymia” is a great word
HYPERTHYMIA — [Noun] A stable, enduring personality temperament characterized by excessive positivity, high energy, enthusiasm, and optimism. From the Greek prefix hyper- ("over, beyond, excessive") and -thymia (from Greek thymos, meaning "mood, spirit"). Unlike hypomania, which denotes a transient, pathological state, or dysthymia, its chronic depressive opposite, hyperthymia is a sun-drenched baseline. It is the engine that will not idle, the scent of perpetual spring in a life without autumn, and the restless, humming energy of a body that does not remember how to be still—a constitution blessed, or perhaps burdened, by a permanent, unrequested solar noon.
