Everything I do now is about growing the pot to have more to give away.

Commodity exchanges have a lot of advantages. One, you are helping transparency. Two, they are not political. It's institutional building. It can survive any environment, in theory.

Possessing things is not that interesting. Living in a grand environment to show myself and others that I have wealth has zero appeal.

California is a place of invention, a place of courage, a place of vision, a place of the future. People who made California what it is were willing to take risks, think outside convention and build.

There was a period of time when I first moved to Nashville, like the first couple of years, that I was just simply lost. I didn't know who I was; I didn't know really what I was doing here. I was meant to be a singer, but I just felt lost. That's when I went on the search for my birth family.

Mum's a worrier, she looked after everybody apart from herself - I think it runs in the family.

I founded 'Point Hope' so that I could accomplish some things I wanted to do for children who had no one to advocate for them, children who had no voice. Since I have been blessed with a voice on the radio each night, I thought I would use my celebrity position and my financial resources to help these kids.

My family values are really, really important.
