Sadly I don't sing. I missed it for a long time, but my daughter Emma said something wonderful when I was feeling blue one day: "Mom, you've just found a different way of using your voice, and that's with your books." In a way, she's right. It's just a different way of expressing what I feel about music, individuality, art and all the things I've always loved.

I've learned a lot of things about myself through singing. I used to have a certain dislike of the audience, not as individual people, but as a giant body who was judging me. Of course, it wasn`t really them judging me. It was me judging me. Once I got past that fear, it freed me up, not just when I was performing but in other parts of my life.

Because of the Thames I have always loved inland waterways - water in general, water sounds - there's music in water. Brooks babbling, fountains splashing. Weirs, waterfalls; tumbling, gushing.

I was named after my two grandmothers - Julia Elizabeth.

Leave every place you go, everything you touch, a little better for your having been there.

Success is terrifying. Like happiness, it is often appreciated in retrospect. It's only later that you place it in perspective. Years from now, I'll look back and say, ‘God, wasn't it wonderful.’

Singing has never been particularly easy for me.
