Frank Sinatra on why his mood swings were critical to his success

“Being an 18-karat manic-depressive and having lived a life of violent emotional contradictions, I have an overacute capacity for sadness as well as elation. I know what the cat who wrote the song is trying to say. I’ve been there—and back. I guess the audience feels it along with me. They can’t help it.” – Frank Sinatra
