"I always tell him, 'Darling, you know I'm going to have to give your mind to science after you've passed, because we're going to have to understand how all these sparks work. When he puts his mind to something, he really gets it done very well. I always ask for his help. One thing John said to me was, 'It's harder maintaining success than finding it.' I've got a few records under my belt, and I still feel like a brand new artist. People still want that truth to cut through."
On "By the Grace of God":
"That song is evident of how tough it really was at a certain point. I asked myself, 'Do I want to endure? Should I continue living?' All the songs are real-life moments. I can only write autobiographically. I put all the evidence in the music. I tell my fans if they want to know the real truth about stuff, just listen to the songs."
On her infamous encounter with Barbara Walters:
"I shouldn't have done the interview: I was playing Madison Square Garden that same night, and I knew that the end of my marriage was coming. I was just exhausted and stressed. I'd prepped everyone that I was running late, but Barbara showed up at the original time anyway. When I got there, I apologized immediately, but then she said to me, 'You know, I've only ever waited for one other person this long, and you know who that person was? Judy Garland. You know how she turned out, right?' I was like, 'Oh, snap! Yes, b****!' I think it's the coolest thing that Barbara Walters shaded me. I just couldn't tell her as we were sitting down for a mega-interview, 'Hey, my marriage is falling apart. Give me a break.'"
