The phrase "fighting vainly the old ennui..." is from Cole Porter’s “I Get A Kick Out Of You.”
We need more ennui to fight. The lazy definition is: boredom. That’s not it. Ennui is more of a recurring sulky lassitude because we know something really exciting and satisfying exists but we haven’t figured out how to participate.
I was riddled with ennui until it dawned on me that there was excitement and satisfaction in writing. I wish I could dance. I’m sure good dancing is the ultimate method of saying bye-bye to ennui.
Cole Porter also wrote “You’re The Top” a song that includes these lyrics:
You're the nimble tread
Of the feet of Fred Astaire,
You're an O'Neill drama,
You're Whistler's mama!
