Despite his success, he was full of self doubt about his ability to write lyrics. He usually spent months on one song and was constantly rewriting them. It took a toll on his personal life: for nearly twenty years he battled an amphetamine addiction and was married eight times. Still, he won three Tony Awards and three Academy Awards, and is inducted in the Songwriters Hall of Fame.
He died in June 1986 from lung cancer.
