I'm more confident now than I've ever been. As you get older, you have to be.

I'm completely in charge of my own life now. Sometimes there's no one there to slap me on the hand and say: 'Stop being so bullish and bossy,' and things like that.

When I'm alone at home, I really prefer to listen to Wagner's orchestral music rather than any vocal music. I find it illuminating not to have to pay attention to voices in the recordings.
