I can't think of anything more crushing than slowly, over time, realizing exactly how wrong you were about someone.
“In '98, I locked myself in my house, went out of my mind and wrote 25 songs. I rarely bathed during that period of writing, I sent out for food, I didn't really venture out of my house in three or four months. It was a hell of an experience.”
“When I got finished, Gershwin paid me the ultimate compliment. He said, 'Boy, even I couldn't do that.'”
