I've written what and when I want to. It's been about expressing myself. But with the degree, I had to learn to do everything in a very specific, disciplined way. I am very disciplined, but this demanded a totally different kind of discipline. A real challenge.
It's a very organic process, and it has a specific order to it. I love to write, and once you've written, then you arrange. After the arrangement, you record it, and then you tour it.
You don't have to be rich and famous. You just have to be an ordinary person, doing extraordinary things. I'd like more people to know that it's there. Women's achievements still aren't recognised enough in many areas.
Writing music is just something that I was born to do.
So, the combination of looking at lots of different people and how they react to each other and how they relate to each other and waiting for that inspiration is the thing that allows me to keep writing.
I am constantly being told that I have been a big influence for many people, including other musicians.
I found my sound early on. Look at U2: they haven't changed their music for 20 years. Anyway, many people come unstuck when they try to change what they do and what they are known for.
One of them would definitely be the Nelson Mandela gig, when I played the tribute song for him. He was up and dancing, and he really enjoyed it. It was a really lovely occasion.
Yesterday I was playing Beethoven's fifth, because I love that.
When you're on tour you definitely don't want lots of arguments. It's very important that everybody gets on because you're in close proximity a great deal of the time.
