I'd traveled a lot, was going temporarily insane and became very successful, but there was no one to take that all home to.

I want an autobiography without revealing any personal information.

When I'm working I actually forget to eat. I don't eat sweets because I don't care about them. I have no real secrets. I just realize that as I get older I should stay strong so I exercise more.

So every time I make a new circuit, a new time around, then I change the show. You can't change the songs; people still want to hear "Lady Sings the Blues" and they still want to hear some of the oldies.

So I'm not worried about the emotions I carry with me, because I'm happy that I have them; I think it's good for the work I do. The emotions that are not healthy are the ones you hold inside, like anger.

I'm not really a songwriter - I'm an interpreter. So in a sense I am an actress first and foremost. I act out the songs, and I lead with my heart.

Discipline is a necessary tool to help you get what you want in life. It forces you to stay on center and to move away from the things that are not necessary.
